I own several Aqua Lung regulators (Calypso, Leg3nd, Core) but have no experience with ScubaPro. I found one ScubaPro MK17 EVO S620Ti brand new for less than $600.00. I do mostly warm water and some training in Quarry (55F). I'm looking for some feedback on this ScubaPro setup. Is it a good price? is it a good set up?
