If you have the mechanical ability to do an oil change, you can handle a manual transmission fluid change. It only requires 1.7 quarts of fluid...and there's no filter involved. So if you are doing it yourself, it's not a terribly expensive job. Quality manual transmission fluid does seem to run about $20/quart.
Read THIS post to get a quick idea what is involved in doing this job.
