Minute Man Electronics has them for sale again but I think they only take credit cards. The covers sell for US$2.99 though they have a minimum US20.00 order policy. I'd buy some but can only imagine their shipping rates to Australia.
Minute Man Electronics Hardware for Switches
Ok, Minute man, is going to take a check. (I have no idea why they haven't moved on to taking paypal, But whatever.) I had to order 7 of them, to meet their minimum order. It will probably be a couple of weeks before I get them. (since the check has to get to them ,and then the items has to get to me. ;( ) Anyway's, If anyone needs one of these, or you know 4 or 5 of them, let me know. I would have to charge like $5.00 shipped for them, but at least you wouldn't have to meet a minimum order, and I am willing to ship out side the use. (for a little extra shipping. ) When they get here, I may put up a proper for sale thread, but I just wanted to put the word out there, to get that ball rolling.
Anyways, it looks like I will finally be able to do a replica of this prop.
