I think the sub is pretty much a rite of passage in this hobby. I am currently at 9 different subs from different dealers. My favorites so far are:
Paul's so called perfect (noob like, shallow rehaut case with eta, date in correct position)
$188 Josh ("wok" style, deep looking rehaut, date far to the right)
Josh Beginmariner (noob case, asian mov't, mine has very bad bracelet, crystal is installed crooked, but for $100 delivered can't complain)
Hands down my favorite TTK MBW (beautiful deep and thick rehaut like gen, better bezel than the others, needs a hollow midlink bracelet)
A couple pics just for kicks. From left to right: 1) Pauls So Called Perfect (notice the shallower rehaut), 2) Josh's $188 (hard to see but the rehaut is very conical, looks nice and deep though) 3) TTK MBW (has it right, look very carefully at the deep and THICK gen like rehaut)
They are all very nice and you pretty much can't go wrong with any of them. If I could do it over, I would personally go straight to the MBW (I would have saved a crap load of money)
