I agree with above. See about getting used if you need the budget.
I actually recommend new divers get aqualung or scuba pro as it is easy to get serviced almost anywhere and is good quality. I always recommend getting environment sealed regs as.they also protect against silt as well.
I also prefer a back plate wing.
Is there a place or people local to you where you can rent or borrow a bpw to try? It is in general better to try any bc prior to buying.
Used definitely seems like it could be a good idea. It's just a little daunting because there is already so much out there and I have minimal knowledge.
