While I haven't bought from them in particular, I pretty much only used generic ink in my Epson 820. For about 1/6th the price, you couldn't beat it. I always got mine from ebay. I never had a problem with them except one cartridge and the seller exchanged it without a problem. Although, my printer just died because the print heads clogged, so I'm not sure it wasn't from the generic inks, but it lasted ~4-5 years overall and with the prices of inkjets, I'm sure I saved money in the long run even if they did lead to the premature death of my inkjet. Now I have a laser printer and I love it.
