You don't happen to dive with the Mass Bay Divers Club, do you?
no.
I think Northeast scuba in Chelmsford sells bp's and wings if you want to see them in person. I would avoid getting a "tech" style bc.... either go cheap with a basic jacket (can't believe I said that) or go bp/wing. What have you been renting? Do you like those?
My philoshopy is simple: The more you dive, the more you will realize what you want from your gear. Without knowing that, you will make purchases that you will probably regret and end up replacing gear down the road. Therefore, the best solution is rent as many different setups as you can to help yourself make an informed decision. In actuality, this is next to impossible. Next best thing, in my opinion, is to at least dive with many different people to see what they are using. Ask them what they like about their gear. Ask what they don't like. Ask if they would purchase something again. In the meantime, it is probably most economical to purchase a simple jacket bc... gets you in the water without incurring rental fees... you can probably find one on Ebay for 100 bucks or so. That would probably pay for itself after a dozen dives vs. renting, allowing you to try and determine in what direction you want to go.
I have done the jacket to bp/wing conversion. I was saved from stopping along the way to purchase a zeagle because my wife got one, and I'm not impressed. Many have gone this route. Others have tried bp/wings and have not liked them for whatever reasons.
You don't know, at this point, what you want from your gear... until you do, it is probably best to not make big purchases. Hell.... if you can wear a size large bc, I'll sell you my old jacket bc cheap...
Many people will tell you what to buy. You might be happy with those purchases, or not. The only way to try and insure happiness with you gear selection, is to have a pretty good idea of what you want from your gear, and that only comes with time and experience.
By the way... welcome to the board. Somebody is always posting local dive plans here (or in the New England forum, anyways) and all are welcome.
