The McMaster-Carr unit is out of my price range. What about cleaning solutions?  I've seen a mixture of Simple Green and water recommended.

I have a tabletop ultrasonic cleaner that I use for carburetors and 
similar size pieces.  I find it does a pretty good job, which becomes 
evident when you see how funky the cleaning solution becomes after a 
while of work.  The one I have will easily accommodate a Corvair oil 
cooler.  I've used a 25% solution of Spray-9 cleaner-degreaser and water 
with good results, and Simple Green ($$) seems to work ok but no better 
than Spray-9 (Walmart has it) which works really well on most anything 
whether it's oily or greasy or just plain grimey-dirty.
