[LAU] hardware compressor-EQ-Limiter

[millward]

Can anyone advise on a good, but relatively cheap,
hardware compressor-equalizer-limiter ?
I'm told its best to clean up the input signal rather than
having to try to clean it up after its already recorded.
That's why I'm looking for this hardware, at a reasonable price.
I'm not looking for the high-end professional stuff.
 Any information would be most welcome.
