That is a Titan LX with the environmentally sealed first stage and it has the snowflake on the second stage. It is a capable regulator including cold water. The second stage is pneumatically balaned but does not have the breathing adjustment knob, just the Pre-dive and Dive lever. I have one exactly like it and it is a good performer and as reliable as the Rock of Ages. It is fully serviceable by any decent AL shop. The first stage internals are no different from current AL first stages, the second stage is easy to service and kits are available. This regulator rated the highest performance ANSTI category and was a best buy choice for Scuba Labs I think it was or something like that.
Consoles are so dated and non-cool and the octopus is a simple downstream second stage, adequate for sport divers.
$150 at most. I would give nothing for the console because you need a nitrox capable computer instead, on your wrist. If that is a nitrox capable computer then, okay, maybe $200, I guess at the outside.
