My dealings with Martin Instrument have not been good. When I bought my company, I spent 24K on used equipment. The first 6 months, I was returning my Rover for repair. in December my rover sat there for several weeks, I received over 1k in rental fees, for the loaner. They don't have intergrity in my opinion.
