It's funny David, I have lived near water all my life and so had access to scuba shops. I didn't give much thought to what folks in the interior or southwest of our country do if they need scuba tanks serviced. Electric motor or compressor starting really make sense given such locations.

I suppose you're right about AMT needing to mark the Eliminator up in order to turn a profit. It still seems a bit pricey for a piece of support equipment.
