Good on you for not being put off!

BTW if you go down the buying route one possible, likely cheaper but as yet untested alternative to the Tormach might be:

SKYFIRE CNC

Website is still being built, it's that new. There's a huge thread on cnczone where the manufacturer details the entire R&D process: this page has some pics of pretty much the finished item...

Think that may be the smaller SVM-0 model - there's a larger SVM-2 planned they say with BT30 spindle which will be a more direct Tormach competitor: some details here:
