Anyone used a continuious ink system for their printer?

[QueBert]

I saw a Continuious Ink system for my Printer on Ebay (Epson r200) the idea interested me. As the inks are pretty expensive with how much I use. And refilling the carts are a pain in the arse. My question is how anyone had experince with these? I'd love to not have to worry about ink levels for months at a time. I like the idea, but it sounds too good to be true, even for the price ($250) I'm warry that it's not gonna be as good as it sounds.

that's what I'm talkin about ordering, just looking for something to keep my ink flowing without money or hassle
