To save endless questions (and people searching through pages and pages of torch threads

) I thought I'd chuck together a very quick thread with links to the top products in each price point. Feel free to dispute anything below and we should end up with a list of only stuff worth looking at.
A bit about overseas resellers:
DX.com: Good range of products, prices are good but shipping times can be slow (anything from 2-6 weeks).
Fasttech.com: Fairly quick in terms of shipping (~2 weeks normally) . Excellent prices and still willing to sell Li-ion batteries although they must be sent via surface mail which takes 2-3 months.
Coupon code BLF gives 5% off most torch related items.
Aliexpress.com: Chinese version of eBay, you pay up front and the seller doesn't receive the money until you confirm arrival. See the SN6X-2s link below for the Maxtoch seller.
Torches
A60 - single 18650, narrow beam, long range, quality is not always the best but very good price

Convoy C8 - single 18650, good output but medium range (100m for bunnies), good size spot so good as an all around .22 light.
http://www.fasttech.com/products/1601/10002364/1272100Latest version of the SN6X-2 – takes 2 18650s, excellent range with good run-time, in the right conditions you can see rabbits out to 200m with these.

Check out Mudgripz's reply below (number 11 and 18) for info for troubleshooting if your having issues.
Headlights:
Zebralight – Reliable and well thought out headlights. No zoom function but waterproof, lightweight and has excellent run-time and output for the size (18650 version same weight as a Lenser H7) with enough grunt to see something 100m away if needed.
http://www.zebralight.com or via Trademe
Ultrafire H6 – cheap alternative to 18650 Zebralights, still excellent but a couple of minor design issues.
http://www.ultrafire-shop.net/UltraFire_Shop.php?view=productPage&product=133Somewhat bulky but reasonable run time and range make it a good all rounder.

Lenser H7 knock-off – identical a Led Lenser H7, just as prone to eventually wearing out as the earlier H7 is but without the warranty. For all of $12 its worth grabbing one for the glove box.

Batteries (18650) Note: the Panasonic cells are 1-2mm longer then normal and very slightly wider then normal so may not fit in all 18650 torches. They should fit in all of the above with minor alterations to torch tail-cap internals. Another note on Chinese cells: often the claimed capacity is "creative" marketing, the best Japanese cells are ~3000-3400mAh so anything claiming more is bogus.
Generally any of these batteries can be found on Trademe as well (for twice as much) so worth checking if you need them in a hurry. Generally anything less then $8 per cell off TM is garbage.
Trustfire 2400mAh (2300-2400mAh real)

Panasonic 2900mAh (2800-2900mAh real)
http://www.fasttech.com/product/1141000Panasonic 3100mAh (2900-3100mAh real)
http://www.fasttech.com/products/1420/10001980/1141103 Panasonic 3400mAh (3100-3400mAh real, best 18650 on market but no where near as cheap as Trustfires)
http://www.fasttech.com/products/1420/10001980/1141104Batteries ( Low Self Discharge or LSD AA and AAA) AA and AAA rechargeables of old need recharging every couple of months regardless of use. Newer low self discharge cells retain around 80%+ of their charge for a year so don't need to be recharged if they haven't been used for while.
Some of the better brands are:
Sanyo / Panasonic Eneloop (no longer sold by Fasttech)
Camelion Alwaysready
Panasonic Infinity / Evolta
Maha Imedion
No links buts you should be able to find any of the above on Trademe, eBay (watch for counterfeits) or the local supermarket.
Enelong - Eneloop knock off... not as good as Eneloop but very cheap (may need to be shipped via surface mail).

Charges. You get what you pay for so I would advise against buying the cheapest you can find. Many of the cheaper models do not charge batteries separately and do not automatically stop charging once full which can pose a fire hazard and destroys the life and capacity of the batteries.
Trustfire: basic model, does the job, does not charge each cell independently though.
