Some vendors, and oddly enough some areas of the country seem to be in a time warp. There is a vendor in Texas I completely quit doing business with. I like their stuff, but they are SO SLOW ! I also have trouble getting electronic parts in general. With no good source locally, I try to buy stuff like relays, switches, electrical plugs, etc. I find a lot of the vendors from out of the country do not know the basic specifications. Such thing as sending me A.C. relays when I ordered D.C. for example. But I once waited 9DAYS to get 2 D.C. relays from right here in California. 80 miles away ! Vendor was angry at me for giving them a poor review on EBay. ...J.D.
