I started using PVC blow-off tubes. They are cheaper than all 1.25 x 1" vinyl tubing, and you can take them apart to clean them. You still use about 6" of 1.25 x 1" vinyl tubing, but you use PVC pipe and elbows to make the 'bend' back down to the bucket, so no leakage problems.
There is a crummy picture in this post here
. I got the idea from someone else on the board, and he had some really good photos. But I can't remember now who it was.
EDIT: Found a better photo in Brewiz's gallery here
. But there are better ones out there still somewhere.
