Yes definitely get pedals.
I'm using the Saitek Combat rudder pedals.
So far I'm pretty satisfied with them.
Pretty much my only problem with them is the following:
The amount of force required to operate the toebrakes is (far) too low. It's acceptable, but imho too low. I have not explored on how to increase the force required (if at all possible..), because the pedals are buried deep in my cockpit, and it'll take a good amount of time to extract them. So for the time being I'm leaving them in.
Another mayor reason I went for the combat pedals (for example) versus the other Saitek pedals is the fact you have your feet on the floor, and not completely on the pedals themselves.
This was a mayor requirement for me, ergonomics wise.
