I'd be thinking about your scope too, as this is what really make or breaks and FT rig, you'll not go far wrong with one of the new green turreted big Nikko's (10-50x60). Add a larger sidewheel, and almost any modern PCP will do you proud.
If you're buying new you want to be looking at something like the S400, in standard form the stock might need some work (deeper forend, raised cheekpiece etc). There's the MPR FT version too, which is more suited to FT out of the box, but these are a bit unproven at the moment, good ones and bad ones going around.
If you're looking 2nd hand, the PT is a very good buy, don't consider anything without the MK3 reg unless the price reflects it, they come in various forms and there are very few standard ones around these days.
Nice example Here and a good bloke to deal with.
If you want to go down the springer route, prepair to miss more targets Its very hard to learn much from missing a target with a springer, as its quite rare you see the pellet land due to the recoil, so its hard to figure if you're giving enough windage or getting ranges right. My choice would be an older HW77/97 or a MK1-2 TX200, the new guns are not quite as sweet, plus buying a 2nd hand springer will mean you dont have to go through the running in period.
The best thing to do is get yourself to as many FT shoots as you can, and try out plenty of kit before commiting yourself to buying something.
HFT is another target sport (the H stands for hunter), the same targets are used, but the max range is 45 yards. No range finding or scope twiddling is allowed, so its more guestimation. The main shooting position is prone, rather than the FT sitting position. A lot of the skills are transferable between the two sports, and its possible to create a rig that will shoot both well, albeit with compromises.
Hope this helps a little, don't hessitate to ask any further questions.
