O'Three is top
After that, Otter, Scubaforce, Deep6, USIA, myriad of suits in the bag suit range that are all close enough. I'd probably buy a scubaforce if I was in the market for a new bag suit, but if you aren't flying, then just buy an Ri-200 from O'Three and call it a day
O'3 now makes Trilam suit too. High end with most options as standard yet still reasonably priced.
