Hi all,
I have also tried using those cheap, black plastic tubes from Home
Depot--They're the ones used for draining water away from a house.  I've
had very good luck with those ones--my little guys *love* them, and you can
buy elbows and tees and make a giant maze with the help of a good knife.
Plus, you can change it around every once in a while--that one's funny,
because when Chopper went through for the first time after I did that, he
shot out and started dooking and war dancing like crazy!  I think he liked
it.  Best part is, I think I only spent $15 on the whole thing--something
like $3 for 10 feet of tubing and then $1.50 each for elbows and tees.
 
Dooks to all,
Chris, slave of weasel
