You can pretty much use any effects pedal, including the ones that cost $12 on Ebay. They all do the same thing and work the same way.
Good luck,

Tough keep in mind, that when using the more expensive ones, the mechanical part might feel much more fluent, in general the cheeper pedals give a cluncky feeling...
For anyone using pedals a lot, i would allways advise test before you buy...
