You can buy, for about a tenner, a little device that resets the chip when you fill it. I have never used one, so cannot say how effective it is.
I buy cheap cartridges on the internet at about £2 to £3 each. They seem to work just fine.
Epson is now producing a printer in which much larger ink containers can be used mounted on the side of the printer and linked by flexible tubes to the print head. These contain enough ink for thousands of pages and seems a much better idea than moving cartridges and head about. You are intended to refill these containers yourself.
I'd expect the printer to be a bit faster. A lighter print head means less inertia so it can be moved about faster, but I haven't seen any reviews of them so don't know. Probably worth a look if you do a lot of printing.
