This place is going to be a little easier to deal with than eBay, and I can personally guarantee the quality:

Great place, just go ahead and buy direct from China. 2 of the 3 plants worldwide that make LiPo batteries are located in Korea, just north of China.
One of those plants sells direct to hobbyking (Zippy LiPoly).
I have 3 of these, all work flawlessly:

There's a Warehouse in Germany for the HobbyKing place, you should definitely save tons on shipping then. There are TONS of batts on that site, it'll take hours to look through all of them. Just do a search for hard case in the search box, that'll give you all the packs your looking for.
I am not affiliated with hobbyking, just a faithful customer. I like that you can buy the same products that major RC companies resell at the same price the major companies buy for.
