I just made my own using the following compressed air filter:

In about 1000 miles I collected a couple of ounces of oil (about 1.5" in the bottom of the home made catch can.
However, the plastic innards partially melted from the heat. I'll try to mount it farther away from the engine block. This is really too bad because this $40 in air filter seems to have done as good a job as the $100+ catch cans. I may just have to bite the bullet and get one if heat continues to be a problem.
