I really woundn't go more than $250 for everything and thats even if the BC and computer are alot newer than the Conshelf.
One other thing to check is for small cracks on the yellow octo case where the hose joins....USD had a quality issue with the yellow plastic.
As for the value/performance of the new Aeris vs. old USD.......you wouldn't be able to tell a difference between the two on performance, although theoretically the nod would go to the balanced diaphragm of the USD over the unbalanced piston of the Aeris.
Value?....$150 for the Conshelf includes octo and gauges with a compass.
