Very good prices and fast service every time I've used them.
Their Brother-compatible Ink Cartridges have never given me a moment's trouble either, and they're about 25% of the price of the branded ones.
have a look around for continuous ink supply systems. it consists of a big (100ml of each ink) reservoir connected by tubing to resettable cartridges which replace the normal ones. once it's set up it's a doddle to use. when a cartridge registers empty you go through the refill cycle, only all you do is unplug the cartridge then plug it back in. ebay seems to be awash with them (and ink for them).
