How difficult is it to replace a ac compressor on a 96 Tahoe 2wd?

Well the compressor is not hard, I think (without looking at it) it is like 4 bolts, and a couple of connections. The problem is that most good A/C guys will tell you to replace most of the system at once or when you replace the compressor, you will have to replace most of the parts, one after the other, and perhaps eventually replace the compressor again not to far out... From what I understand... the compressor tears parts up inside, and sends them through the lines to the other parts, eventually eating each of them up.
