Its a personal choice, but I recently got an Epson CX3600, does all you need and also acts as a stand alone copier without the computer being on :-) as regards cartridges it has 4 individual ones, but if you are prepared to invest in compatible cartridges as opposed to branded ones, you can get some very good deals, I recently got 3 sets of the 4 cartridges for approx �12 and they work perfectly well.
Dont know where you are based, but Comet do a good deal on-line for these (they do charge more in the shop though as my father also got one as he was a bit wary of online transactions),Heres a link anyway
