I would add a caveat to this. When you replace just the joints and boots, quality control is completely in your hands. You can inspect the parts for defects, and ensure proper lubrication and installation. When you install a pre-assembled unit, you put the QC solely in the hands of someone whose only goal was to assemble as many of these things as possible before lunch. A warranty is great, but if the part fails prematurely you still have to remove the thing, take it back to the vendor and re-install the replacement.  At the very least, when installing complete axles, pull back the boots and check for proper lubrication before installation. I've never had a C.V. joint I have installed myself fail, but I have had a rebuilt axle fail (on a vw Quantum), the low cost was negated by my having to do the job twice.
