Your best bet if you are going to get started on one would be to read through the 1000 Already Answered Questions Pages. Its been around for a long time. It just sucks that some important info, points to now dead websites.
If you are going to go with a 2g Talon, I'm would suggest finding a TSI (awd turbo) manual trans, doing a swap is simple, but for the price of everything to complete the swap, you are border-lining on price point of being able to buy another dsm... If you can find one that has been worked on, double check to see if they did an engine swap, you would want a 4g63 6bolt(bolt count at the flywheel) and not the weaker 7bolt one.
Just like buying a VX, take your time and search local dealers, local car classifieds, ebay, craigslist and so on till you find the one you want...
