WE re-plumbed the "Pheasant Shack" with pex and wouldn't use anything else.
Do it once with pex and don't ever worry about freezing & bursting pipes ever again. It expands if the water freezes and then returns to original diameter. Quick attach couplings makes remodel jobs quick and pretty painless. Some of the quick-attach couplings are expensive, but you don't need any tools other than a tape measure and a PVC pipe cutter. I tried a hand pruner once to cut pex, but couldn't quite get the 90* angle consistently.

I re-did all the rough plumbing in my 100-year-old WI house a few years back, and I was amazed at the results. Hot water arrives HOT 3 storeys above the water heater in seconds, cold water is COLD. Add to that the expandibility, so your pipes can't ever burst due to a freeze, and there's simply no other way to go.
