Mbox, M-audio, What!?, Need help deciding Options

[xingu]

There's a handy button on the 428 called the Input Monitor, which gives you a direct analog signal, bypassing the software and thus giving you "zero latency". I have a 428 and hardly ever use this feature unless tracking things at very fast tempos. The regular latency is minimal - audible, but easy enough to deal with (you should have no problem getting used to it.)

I don't know what your measure of reasonably good quality is, but assuming your input signal is of decent quality, you should be satisfied.
