Many LDSs will sell you hangers if you ask. The standard, thick wetsuit hangers run between $10-15 at most LDSs I've bought them.
My budy, his wife and I have about 12-13 BC hangers, 9-10 wetsuit hangers, 2 'big-shoulder' dry-suit hangers and 2 hood/glove/booty drying hangers between us...
I got a bunch of BC and wetsuit hangers at a scuba swap meet cheep (about $5 each) and the rest just bought from our LDS.
We just clean/rinse our stuff and hang it up in his outside (enclosed for security) shower and move it to the SCUBA closet when it's dry (he lets me keep my stuff at his place as I live in a small apartment.
