What do you mean by "affordable"? I have a friend whose whole system cost $600; another spent multiples of that on a power cord.
A Mutec MC-3+USB would do the job. If you can find one, they run about US $650 used. But if you want to try before buying (and I would advise that), a used one is about $1200.
