I got the utec used for 500 bux. the egt you should be able to get for under 200 new. For a wideband, you can get one for 350 new. The utec manual is a good place to start, and wrx hackers.com has a lot of info. there is also a quick tuning guide that pretty much goes step by step with the whole process. I use an old laptop that I got off of ebay for 175 bux. it doesn't need to be really fast. I was using a p2 266 and it was fine.
