My next wheel will be the Fanatec GT2.
It aint cheap, but if you are serious about your racers - which if you are gonna be apying a monthly fee to iracing i presume you are it is worth it imo. Sack off the gearbox (you still have flappy paddles) and get the standard pedals - not the aluminium ones with force feedback) and it comes in around the 300 quid mark.
But having had a go on it, it puts my wheel to shame.
If you want the all singing all dancing one however you need to add another 100 quid to that.
The guy above is right however, placement is key. You do not necessarily need a gameframe or such like, but a decent mount on a computer desk or what not is critical. I personally have never got on with a lap mount and if it was that or nothing, i would not bother.
If however 80 quid really is your limit (I always say i have a limit, then "rearrange" my debts and then ignore it

) but if it really is your limit, then, no a clutch is not essential on iracing there is an auto clutch aid you can enable.
The driving force GT is a capable wheel, and you could always upgrade it in the future with an aftermarket set of pedals with a clutch if you wanted - I am fairly sure you can do that on the pc but do research that 1st..
