Best Epson-compatible inkjet cartridge

I have an older 4-color Epson Stylus printer that still produces nice photos on glossy paper. Costco does not carry the Epson brand replacement cartridges and I would like recommendations on the best and most cost-effective knockoff brands. My needs are mostly non-critical photos and utility color printing.

So far, I haven’t found any good knock-offs or refill kits. If you don’t care about ink leaks in the printer or poor quality prints, try a no-name.
