Anyone know about porsche replica kit cars?

I have been helping a friend of mine build a cobra kit car, and i was wondering if any of you have seen kit cars based on the porsche 550 spyder. My 911 is on the upswing of its restoration and im looking for another project. I thought one of these speedsters would be a fun car especically with a 3 litre flat six. Thanks for any info.

There are links to Chuck Beck's web site (probably the most popular spyder replicar maker) and lots of other info.
