That seems sensible! I service my cars and some friends cars out of a small space in Shrewsbury. I've done plenty of subaru work from engines to gearboxes. I've owned 3-4 of them but have since moved away from subaru with my personal cars.
FYI, if you have that gearbox on the bench and can't figure out what's wrong with it... go to Bill @ DSG. He is by far the most competent and experienced gearbox/differential tech on the northeast. Ironically probably the cheapest too.
