Closed 30 pin SIMM sockets, ideally low profile (20/30degs)

[Tchucolate]

I need to replace some SIMM sockets on an memory/SCSI card, I think I can get away with 4 slot, but ideally Id replace all 16 slots. Does anyone know of a source that is selling these at a reasonable price. I found a supplier in the USA that sells them for $2.80 a pop, but sadly, they will ONLY deal with a business, with a minimum order of $400 + UPS delivery, so not viable for my case.
