You could buy a Fanatec Porsche 911 GT3RS Wheel with Clubsport Pedals (wich are brilliant) for 300€ but you wouldn't have a Shifter. The Fanatec shifter costs 50€.You could also buy a G27 from Logitech for less then 300€ (depending on where you buy it). It has a 6Speed H pattern shifter and nice Pedals too, wich aren't as good as the Fanatec Clubsport ones.
The Pros and Cons for both Wheels :
911 GT3RS & CSP(Clubsportpedals):
Pros: -Very Strong FFB (some people say it's better then the FFB of the G25/27 and DFGT)
-Very good Pedals (changable spring strength and brake pedal with loadcell, pedals are made of metal and they dont have potentiometres, wich would have wear, that means you could use them for the rest of your life)
-Nice Alacantara Leather
-Led display
-Belt driven FFB (pretty quite too)
-Good H-Shifter
-2 extra Vibration motors (a big one for FFB and 2 for the Vibration)
-Has a seqential shifter
-Many buttons on the wheel
Cons: -Many wheels have decalibration problems
-Some people have bad experience with the Fanatec support
-Costs a lot
-You have to pay an extra 50€ for the shifters
G27 :
Pros: -FFB is also quite
-Costs less then the GT3RS
-Nice leather
-H-Shifter is good too(but maybe not as good as the Fanatec one)
-Good FFB(but as said before some people say (also the guys from SRT) that the FFB of the Fanatec wheels is better)
-Shift indicator
Cons: -Not belt driven FFB
-No LED display
-Worse Pedals
-No seq shifter
-No vibration motors
-less buttons on the wheel
I hope that helps.I have a Fanatec Turbo wheel and I like it. It never happened that the FFB isn't strong enough. I don't have problems with it.
You could also buy the Clubsport pedals and use it with the DFGT if you don't need an h-shifter.Then you would have a nice wheel, nice pedals and a seq. shifter.You could also buy a used SST or Act Labs h-shifter or a FFB Joystick and use it with the ffshifter tool as an h-shifter.
300€ is a lot of money and there are many opportunities how to spend them. I hope that in the end you are content with your new wheel/pedal/shifter combination.
