I've only got two kits from EVIL-bay and had my brother-in-law and good friend bid and purchase them as they have Pay-Pal accounts. I really need another kit, parts, tools, etc. like a need another hole-in-the -head and that's why I myself won't venture into that territory. So far it's working really good for me.
I know there are LOTS of guys who shop the "bay" and if it works for them, that's great!
