Which protection circuit should I buy for my 18650 cells?

DEMON PIE!
See title. I'm planning on using two 18650s in parallel with a step up regulator for my portable. My portable will probably only consume about 1000mah. It should hopefully have about 5200mah total.

I just have no idea on what protection circuit to use. Please help guys, I think the battery part is the hardest for me in completing my portable. I definitely don't need my batteries blowing up on me! :sweat:

EDIT: Or is there any way I can use these and wire them in parallel? http://cgi.ebay.com/2-x-18650-3000mAh-3 ... 3a5599be89
