Tom: It would surprise me if there were no dealers at all for ProAc in an area the size of Seattle. Audiogon has contact info for just about every manufacturer off of their home page and they do have a listing for the ProAc distributor. You might want to give them a ring and find out who handles them in your area.
One of things I enjoy about the 2.5's is precisely what you're asking for -- sweetness in the mids and highs, and a huge soundstage. Also, they have a wonderful bottom end, which is pretty stunning considering the size of the drivers, and isn't matched at all by the GP's. As I mentioned before, I think very highly of the GP's, and Sonus Faber in general, but I found the ProAc sound much more to my liking.
Either way, they're both very good speakers so its hard to imagine you not ending up happy whichever way you go.
Happy hunting...
