Its really not that hard and can be done in under 4 hours. If you hane a descent set of basic tools you should be good to go. I have a how to on here that explains the boot replacement process. As long as you don't run around to much and the cv's are not making any noise re booting shoild be all you need.
As a reference my local Isuzu dealer wanted $1800 to replace both cv shafts. If new shafts are needed the Empi's can be bought for about $75 each. Mine have held up well.
