That regset and BC are worth around $250 total. I'd dive it all except the octo. The BC is actually pretty nice: Aeris 5 Oceans . Note that there is someone selling new old stock ones on ebay for $170.
Also note that you'll have at least $100 in service costs, check with your local dive shop for a better estimate. You will not be able to get a self-service course for Mares regs, although normal service parts are available over eBay.
So whether it's a decent deal all comes down to the tanks and how important it is to you to service your own regs.
