As a non-engineering but arty type I thought I might give this a try as I'm more the get-stuck -in and just do-it type and really don't fancy spending hours with a cad design program and then further hours refining and printing the design. At £99 it's kind of within my christmas present budget and I fancy the ability to just throw something together.
Since then I've found this which is even cheaper!
Definitely in the just-buy-it range!
