drchris33,
In regards to diagnostic equipment, most schools usually have reps. visit with student discounts. The discounts are usually pretty good (I have an uncle who works as a purchaser for Maine Medical Center and I was going to get the equipment through him, but after comparing the prices - he told me that we were getting a deal through the reps ... so I went with them). Ask around at your school, usually one of the clubs (Family Practice, etc.) hosts the sale.
As for the OMM Table ... try ebay?
