I've started to get things like this custom manufactured from overseas 
suppliers...  I burn through about 40-50 24VDC 2A supplies a month and 
was having similar issues until I found an overseas source.   Last batch 
I got 300 with the connector/polarization I wanted for under $10 each 
delivered to my door, complete with power cables, and in a nice little 
box containing the supply and the cable all ready to go.

Now I just have to deal with the 30 day lead time, which is definitely 
manageable.

I would recommend digging through globalsources.com, and other similar 
sites which list these types of devices, and contacting the 
manufacturers.  I can also provide you the name of the vendor I use if 
you'd like.

In regards to the polarity issue, I'm not sure what the input circuit 
looks like, but perhaps having the manufacturer switch to a bridge 
rectifier in the input circuit would solve all your potential and actual 
problems.
