I have the DSS SS BP and LCD30 wing that tbone mentioned. It has worked fine for me for traveling to warm water destinations. I pack the BP, wing, my 3/2 wetsuit, regulators, computer, and mask in my carry-on bag, so the weight has never been an issue. With only those things, the carry-on is not that heavy anyway. I put my fins in my checked bag.
I have also used the same rig for diving wrecks off the Outer Banks and for single tank diving in my local quarry (usually 38F on the bottom). A 30-ish pound wing and SS BP seems like a pretty good do-it-all rig for single tank diving - to me, anyway.
That said, I have more recently acquired a Hog 23 # wing and retired the DSS wing. I really like the smaller size of the Hog. The Hog might not be enough lift for some specific dives, so I will keep the 30 # wing around. But, for me, it's more likely that anything where the 23 isn't enough I'll be diving doubles and a dry suit, so that's a different wing anyway and the 30 probably isn't going to get used any more.
If I were buying new, today, and wanted a BP/W to do it all, I would most likely be looking at a Hog SS BP and their 32 # wing and save $100 - 200 or so over the DSS rig. I got my DSS rig used, for cheap. Otherwise, I'd probably would have ended up with a DGX Gears or Hog setup in the first place. DGX has a complete rig for $299 or $309 with a SS BP. But, that is a 25# wing. Only you can decide if that much lift is enough for you and what you want to use it for.
