I have a ScubaPro neoprene drysuit, that has proved to be a decent purchase -- very easily repaired and maintained, a bit like the design of the old O'Neill Super-suit.
Shoddy design and / or construction seems to the state of affairs with many manufacturers nowadays. Even famed O'Neill's, whose 7 mm suits I have used for years, could use improvement, when it comes to suit finishing, The overlapping neoprene edge, surrounding the back zipper is basically unfinished "raw" rubber, just guaranteed to catch; and I have yet to see any suits, without those telltale little chunks of neoprene missing, from repeated entanglements . . .
