Re: I need an inexpensive compressor..........
In that price range, I would go for a Boss CS-3.
But, in my honest opinion, compressors are seriously affecting your dynamics and raising the floor noise, it worths it to get a good compressor from the very beginning.
I've got 5 different compressors (Boss CS-2, MXR Dyna Comp reissue, MXR Custom Comp, T.Rex CompNova, Mad Professor Forest Green Compressor) before I went to the final one: the Wampler EGO Compressor.
Wampler EGO Compressor has anything you will ever need in a compressor and, it's quiet enough. From squeezed to transparent compresison, to parallel compression (Like the Barber), to sustainer (like the CS-3 and Forest Green), to a blend of everything together.
Tag price is $200. If you register in their forum as a member, you got a discount of $20, so, final price would be $180.
You wouldn't be never ever in the search of a better compressor (as I did 5 times, expending way more money).
Just my 2 cts.
