It's been some time since I ordered my last batch but I'd give them a call. Last time I ordered I talked to some in Inside Sales. The 1500's came 6 to a case so I ordered a case. Worth a shot perhaps.
re: evolutionbb ... I posted because I contacted them already (couple days ago) and they said
they no longer have a relationship with the enclosure company.
So, IMHO, not worth a shot.
