These look good to me as an integrated option, but surely you will need a PC anyway for designing what you are going to be cutting /
Assuming you will need some sort of PC anyway look at the cnc drive one with the built in BOB http://shop.cncdrive.com/index.php?productID=1009. Pretty cheap option and UCCNC is good too.

I run my machine on a pc worth about £100 with a UC300 eth controller and UCCNC.
