For single tank, I really like VDH. I have their 18 and 35s.
But, if you want a wing in the 30 - 35# range, I cannot make an argument that the VDH is worth the extra money compared to the (relatively new) DGX single tank wing.

Also, I have the same BP that VDH sells. I like the DGX SS BP better, because it's more flat - which is nice for single tank use.
Their package is hard to beat at $359 with a SS BP.

That said, nobody sells a package that has a harness I would use. I would just buy a BP, a wing, and the webbing and pieces-parts for a harness. Otherwise, I just end up replacing almost every part of a pre-packaged harness with pieces-parts I like better anyway.
Also, a number of the vendors being discussed have really great customer service. But, I don't know of anyone that has BETTER customer service than Dive Gear Express. And, I don't know of any other vendor that has a Return Policy as good as DGX's. DGX Return Policy is lifetime satisfaction guarantee. You buy anything from them and you can return it 10 years later, thoroughly used, for a full credit, if you are not happy with it.
I would say that if you stiff like them that once or twice, they're probably going to black list you from future purchases. But, for example, if you bought their BP/W package and had a legit problem with it after a year or two, they are going to take care of you. Buying from them is basically zero risk.
