I've never been to Noe Valley Music, even though I live in San Francisco! (I may go there soon just to see what it's like.) There are a bunch of other shops in the San Francisco area, though. I bought my first ukulele, a Kala solid mahogany concert, at
Music Works in El Cerrito (East Bay), but I'm not sure if they have high end ukuleles there, and the place doesn't have much of a website. You could email the owner at
ecmusicworks@yahoo.com.
As someone already mentioned, your best bet in the Bay Area might be
Ukulele Source in San Jose, which is approximately 40 miles (64 Km) south of San Francisco. I've never been to that shop but there are people here at UU who rave about it, from its selection of ukuleles to the very nice people who own it. According to its website, it seems to have access to Kanile'as and Ko'alohas, so maybe the owners could special order a Kamaka. You can email the owners of Ukulele Source at
ukulelesource@aol.com, or leave a message for them through the Ukulele Source website.
Other places to shop for ukuleles in the Bay Area: In the East Bay is
The Fifth String in Berkeley. I was in there once to buy strings. Nice people, but a smaller selection of ukuleles than at Music Works. In Palo Alto, which is about 20 miles (32 Km) south of San Francisco, there's
Gryphon Strings, which lists the ukuleles it has in stock on its website. In San Francisco itself, the people at
Guitar Solo are very nice (one showed me how to resting an ukulele). The shop has a small selection of lower-priced Kalas in addition to a few more expensive ukuleles listed on its website. I think I may have seen a Kamaka or Ko'Aloha there when I stopped in, but you may want to contact them in advance to see what they have.
Please let me know if I can be of any more help. I live in San Francisco and I could stop into some of these places for you. Besides, I've always wanted to see Ukulele Source.
One crazy option: Flights to Hawaii are usually cheaper and more frequent from San Francisco than they are from other places. You could hop on a direct flight from San Francisco to Honolulu and buy a Kamaka or Kanile'a from one of those manufacturer's factory stores on Oahu. Plus, you'd be in Hawaii....
I hope this helps.
