Hmm - after doing some research, the R220 does a decent job without totally killing you on ink, the R260 does a beautiful job but ink costs are a disaster. The refilled cartridges and continuous inking systems for the R260 aren't here quite yet. This is probably why the prices are so high for the R220 and why they are already dumping the R260. A lot of places are listing it for around $75.
However, I found this:

It uses the same cartridges as a lot of other HP's, 3rd party carts and refill kits are widely available. Only downside is the color cart is a tricolor.
