I'd agree...$200 is closer...however if I were shopping for it, I would know that it's $139 with the George Catridge NEW with shipping online...and I can get the cartridges for $40 on Ebay. So that's only $220 brand new with whatever cartridges I want.
I would offer it with the George Cartridge for $120, and then sell the other carts separate, and you probably would get $200 altogether.
