Is this the one for me?

Concerned at how I would go about building something for occasional use in my bicycle creating workshop I took to checking out the Chinese CNC machines on Ebay. The reviews seem fairly positive and the youtube action seems to cover pretty much what I would use it for. Cutting out aluminium dropouts from 5mm alloy, making plywood jigs etc.
I think the time is nigh for buying as I am just starting on a recumbent trike and will have all the steering and suspension parts to make.
Whilst I need a little accuracy, my creations aren't going into space and the alternative is using a jigsaw and a file.
Before I commit to buy, any warnings thoughts etc. This one is already in the UK so no horrid import duty to pay, bonus.
