You'll get what you pay for a CLA, especially with the few people who are factory trained. I've done business with Odess and he's worth every penny. I would be afraid that a cheaper CLA might involve squirting in some lighter fluid and hoping for the best, rather than disassembly and proper cleaning, which clearly takes a lot of time and expertise.
Otherwise, measure your shutter speeds and use a "cheat sheet" of actual shutter speeds. There are instructions on the web to make a shutter speed tester using parts from RadioShack, for $10 or so. Mine works fine and then I attach the cheat sheet to the camera and just use those numbers.
