Thats quite a big question!
What size frame are you looking at?

Out of this probably a 2'x4' bed and about 18" gantry height. :)

Well been looking even more over the last couple of days and seem to have a nice solid plan in my head, with minimal machining of parts and hopefully cheap enough to build and then simply upgrade the sizes as needed. Just tracking down a couple of suppliers of the extrusion and seeing if I can get the linear parts made rather than importing them + tax + vat + shipping etc. More to follow :)
