I ordered the guide and pattern system from them a while back; and got a phone call [from Wendy] letting me know the guide pin/bushing were TOS. They were just about to start another run of them. They wanted to know what I wanted to do about shipping, [to hold the whole order till they came in, or ship what was in stock]. (Most) other places I've ordered items from would just ship what they have, and include a slip saying the rest was "back-ordered". I ordered a bunch of stuff, since most items were on sale.
I look at it this way, if I'm going to order from them, I'll send the $$ to get the whole package, that way I know everything will work together.
