Anybody have any experiences, good or bad, with refilling inkjet cartridges? While downloading free cardmodels from the 'net is fun and easy on the wallet, printing them out to actually build can take a bite out of the hobby allowance! I'm using an HP Deskjet 3740 which uses cartridges 27 and 28 for B&W and Color, respectively. A 2-pak usally costs me just under $40.00! I'm not sure how many pages I should get out of a set of cartidges, but the other dat I printed out a 4-page kit and set the printer to hi-res, and the next time I printed, the internal counter that shows approximate ink levels was half what it was before I printed that model! Thanks for any help!
