Well, I have refilled my Epson 600 several times. All I can say is you do save a chunk of change, but it is a royal PITA to do. To refill a 3 color cart takes me about 20 mins. It makes a real mess if you aint carfull. It makes a mess if you ARE carefull. If you dont fill it just right, it gets air bubbles in it and will not print correctly. I bought a refill kit that did each color about 10 times for around $20 at a computer show. I dont refill any more tho. You can find generic color carts for ~$7 and black for around $5 if you look around. Check E-bay, there are butt-loads of auctions for them. My vote is refill(NO), cheap generic cartridges(YES).
