Does anyone hve experience with Hobbicolors products? Carts look interesting with a plastic screw to seal the fill hole. I've been very happy with MIS inks refilling OEM carts, but I would like another source of carts rather than having to buy new oem carts to use and then refill. The tiny rubber stopper in the MIS carts is somewhat difficult to deal with (echoing Niel's comments on his web site.) Printer is a Canon i960.
