Gotta love that proprietary stuff. Personally I think 250.oo per motor for small servos is high not to mention almost 900 bucks each!!
If they are molex type (white Nylon connectors) find some heatshink tubing that will fit over the connectors then plug them up and shrink it down. If you need to disconnect them just cut the tubing off.
Next time shop around. There may be other solutions out there that don't require a bank loan.
