I recently showed my mutli-touch machine at Maker Faire UK.
Rather than using FTIR I used the rear IR diffused method. This required no custom electronics because I used the CCTV IR illuminators as my IR source. I then modified an Xbox Live Camera to have a IR Band filter and then it was just the table I had to build. I did the whole thing for less then £90 (so about $140) because I had the Xbox camera (but almost any web cam will do) and I borrowed a projector from work!
I made a video of it, you can see how I put it all together at

I also used an multitouch application built by members of the NUIGroup with XNA. This gives a great user experience - very Surface like :-)
Its all in the video so please take a look! My blog has more details - I'd be happy to help others looking at doing this sort of thing so ping me if you need help!
