Best deal anywhere, been using one for 3 years, works great in the wind, will light anything made and holds enough fuel for a couple of months regular use. Only negative is the throttle valve is not the greatest of precision instruments. Bright orange so hard to misplace. All for under $10!

Other good choices are Ronson Jet Lite for under $4 at Walmart and the Blazers for around $35 which are high quality. Jet Lite has a lower fuel capacity which might prove a negative for your needs but hell just take 2 or 3 of them to make sure you don't run out.
