I'm looking into buying a budget CNC router. Id like to build my own to learn more about them but just don't have the time at the moment. Could anyone tell me what they think of this machine ?

The seller is only a couple of miles from me so I'm wondering whether its worth going to have a look but I'm not entirely sure what to look for. I will only need it initially to drill lots of holes in plastic/ thin aluminium sheet. It would be nice If it could cut 15mm ply also but that may be beyond the capability of this type of machine ? Any advise welcome.
