HI,
for value for money, have a look at the Tigullio T52 Hover. It has a good lift value, good size pockets and is well made. It has a waistcoat design with a wing attached. I use one for diving abroad with a single cylinder. I have an Audax Pro wing for diving in this country and I find the dive profile of the Hover is the same as that of the Audax.
Have a look at
T52 - Hover BCD
Go Dive are selling them for £225.
You wont get better for that money.
Good luck
Jacko.
