Good luck Bartee!
I did the PVC pipe, works good for me, but the pipe is not the expensive part, the fittings cost REAL money!
When you slide the pipe into the fittings, mix up a spray bottle of dish soap and water, spray this on the joint as it goes together, makes things a LOT easier, and when dry, things stay together. If you need to take stuff apart, just respray with water and they come apart a lot easier.
