I got my system from Reptile Basics also. The tubing I got from the local pet shop, as it was cheaper (airline tubing for aquariums), and the bucket I already had. Make sure you get the clips to hold it onto the wire, and you shouldn't have any problems. Two days after I installed it, one of the males in a holder bin pulled the line through and chewed it because I hadn't clipped in on firmly enough. The poor things were half submerged for about 5 hours until I got home from work, but they were fine. If it had been a tub with babies in it though, I would have had deaths. And since I just had a bucket, and it wasn't attached to a water line, the water ran out before completely drowning them.

I've only had it about a week, and it's already worth the investment, just because I don't have to fill water bottles anymore. I was refilling every other day, sometimes every day for the tubs with more ratties in them. The bucket so far has been only filled twice, and one of the times was after the flood!
