There's nothing more satisfying than building your own, the forum's own AshG did a series of articles in Complete Kit Car covering his build, he did an evening course to learn to weld (worth considering if you're not used to welding, ignore if you are good at it

) the end result was on our stand at Exeter last year and went down a storm. It might be worth while seeing if back issues are still available.
There's a massive amount of knowledge on the forum, so don't be affraid to ask.
Kind regards
