I'm kinda shocked to see MicroCenter surge again. The one on Steven's Creek feels like a mini, less seedy, Fry's (I may be biased from Fry's terminal years).
Nevertheless, it still took me 10 minutes to get the attention of the otherwise omnipresent salespeople to let me pick up a UCG, and I ended up getting the rest of my setup at Central Computers.
Edit: I'm ragging too hard. I'm glad MicroCenter exists and the in-person selection they offer.
