Be patient, CDM CSEs do show up here from time to time.
I have a pair of CDM 1NTs after upgrading from a different brand - could not make another CDM 1NT or the matching CDM CNT work (too tall to fit in my rack setup).
I went with the CDM CSE (a tad smaller than the CDM CNT) - works quite nicely.
So, I suppose if you can't wait for a CSE to show up, that going the other way with a 1NT would work as well.
