Where to see keris in Bali?

[Gajah]

She who rules decided to go on a four day trip to Bali next week. We've been there already a couple of times, but that was before I became interested in keris. Any recommendations as to where to go to look (and even possibly buy) keris? So far I only found the Neka Art Museum in Ubud.

Sorry if this topic has been covered already, but the search function didn't work for me.
