Hi Sammy
Check out these sites for more FT related stuff:

For FT I would say the scope is more important than the rifle. You will need to find one with good rangefinding capabilities. A good all-round scope is a Nikko Stirling Diamond (known as a Big Nikko) 10-50x60.
A decent affordable FT rifle would be a used Air Arms EV2 mk1. Keep an eye out in the sales section on here and Shootng-the-breeze.
By far, the best thing to do would be to try as many rifles as possible til you find a match for you. I went thru a couple til I found my used Steyr and even then the stock wasn't right so I bought a used FT stock from the sales section on here.
