Keith at the Kite Company in Newport Oregon is a good guy. Very knowledgeable and good at kite repair. He has lots of parts on hand also. Decent selection of factory kites. He doesn't sell Prism kites last I was in there. I like his style, if you ask, he has no problem telling you what he thinks. I always stop in there for a visit with him and buy something if I pass through when they are open. They sell online also but I haven't bought from the online store. They used to make kites a long time ago.

Another vote for Ocean Shores Kites. Their kite selection is probably the best that I have seen, and they carry good stuff. Andy is also a really nice guy, and very knowledgeable also. Another one that calls it like he sees it. He sells online also.
It sounds like both of these shops are barely hanging in there....
Gasworks Kite shop in Seattle was good before they closed.
I read this post about Prism having to cut costs. Something about not going to stock or make parts anymore for old discontinued kites when they run out.
