Ok, this might not generate much interest here but if you don't mind please pass on to any Nano acquaintances you might have.
Product specs are here.
The ports are 1.5" opening with a 2" flange, with an end inlet and a long perforated 1/4" strainer element. I think this makes it either the S10036 or S10037 ($1400 or $1500 retail).
I realize you would need to be looking for one of these for this to be a good deal, but I have two of them for $375 each or $700 for both (plus shipping). No tri-clamp with either.
