I have a pair of FGT3something-or-others (340's?). They're not the best pair of trainers I've ever had, but they're fine. I got them for a bargain from Start Fitness a year or so ago, I think it was 2 pairs for £50 at the time. For that sort of price (and I've seen them even cheaper since) they're fantastic.
There was a thread about them back then - everybody seemed to have a similar view - great for the price. If I was hammering out 20 milers every week I would go for something else, but they do the job for me.
Cushioning is fine, support pretty good, forefoot especially good. My main gripe is that the grip is terrible in the wet. Also they let water in very easily (though let it out again too).
Why not buy em and try em - you can always use them for knocking about in/gardening/slippers? etc. if you don't like them.
