I bought 2 x Galaxy S2 1800mAh batteries and a charger for £9 off eBay and they work without any problems. I know there are 'fakes' out there with regards to the capacities but I have used ebay for replacement universal batteries for years for a whole range of phones and (so far) no problems. As ever pick a seller with good ratings and read the feedback etc and I don't see why you'd have any issues.
Regarding compatibility, I just used the original battery model number: EB-F1A2GBU and searched from there.
