Jeff Rowland Sellers

Yah I suppose its Agon ettiquette.
I think when you post an obvious ad or even in some instances a wanted to buy, both of which have better places to be posted. It is sorta unpleasant to read an overt ad when every one else plays by the rules and pays for them. In your case however it is a vague enough "want to buy" which is not overtly and obviously trying to skirt any rule.
You have your answer that Mofi kindly provided.

There is a dealer link on the Rowland website. Here is a list of the North American dealers:
