As the Best Buy of instrument and equipment stores, I found myself explaining various features of the digital pianos to the sales people, whom I had hoped would actually be educating me, and helping to narrow down my selections based on my needs. Previously having checked out instruments at their store in Chicago, I was amused by the conflicting opinions and facts I got, and could tell that they were pushing certain models based on what they had in stock, or floor models they wanted to get rid of. At this point my purchasing process began to remind me of shopping for a car - I soon found myself in the awkward game of negotiating accessories. In the end I like to imagine this helped me to save money over what I would have spent online. Definitely plan on doing your research before you go.
If you're looking for music or more obscure instruments, go elsewhere. I tried looking for a banjo here, but they had a selection of one, and no one on staff who was knowledgeable about the instrument - for this task I'll stick to mom n' pop shops like Spruce Tree Music http://www.yelp.com/biz/gpcBFpC2umQ9sZfCOqeCGA?fsid=6XLsIgL4z6vFtZSDiO6i0g.
