I've got rubbish pedals from a AUD$25 (about USD$19) steering wheel (the cheaper the better - they're symmetrical, you see) plugged into my Cougar Hotas.
I love them, mostly for when I get my ailerons shot off (happens a lot) and it makes it quite possible to return to base, and occasionally to get a kill or two in the meantime.
You've got some fairly quick and cheap options, without either buying the CH pedals, or making them from scratch - I reckon it's worth it.
