I'm using the ghastly One Spot right now with the ridiculous long pigtail chain... I see pedal power 2 by voodoo is like 130 bucks but I see a boatload of similar units on Amazon for 30 or 40 bux. Brands like Donner and others I have never heard of. Seeking experiences on budget friendly power and a link to Amazon so I can buy today. Thanks, lads.
