I have heard from numerous people about problems with Poverty cranks. I personally haven't ridden them, but I do avoid products that I hear a lot of bad comments about.
That said, if you have 100 bucks burning a hole in your pocket, why not just work on saving the extra 50 bucks for some flat out kick butt cranks like the Profiles? Everyone uses them, everyone LOVES them, and except for a few rare cases, they last almost every rider forever.
You can sometimes find them on ebay for a decent price as well. Actually, there are some on eBay right now for under 100 bucks! Go get them instead of a 'cheap' named product with questionable reliability.
