GM2163	Free from NEB, reasonably hardy
GM2929	Free from NEB, rec- (recF), less hardy
JM110	From various companies
SCS110	From Stratagene, endA- version of JM110
DM1	Gibco BRL
There are probably many others.

All are dam- dcm-.  I've used GM2163 and it worked just fine.
I have no affiliation with any of the above companies.
