I'm newly certified (open water in Feb). I have most of the equipment now, and just got a Geo 2 computer. I'm pondering getting the reg set as I'll probably dive on on or two trips per year (living in Canada I go south!). For the 6-8 dives a year, is it worth spending the $$$, or should the wife and I just rent? Not likely we will do the cold water stuff up here ( wife won't for sure but I could maybe...) I think it's about $50-$60 to do a yearly maintenance... I'm looking at $450+ for a set... Advice??
