Well, on my recent trip to Vegas and San Francisco, I made the drastic mistake of leaving both the battery and charger for my D7000 at home...in Chicago.
I ended up checking out various, sorry excuses for camera shops on the strip which were price gouging like CRAZY. Most places were asking for $100 for an EN-EL15 battery and $70 for off brand chargers.
Ended up here in desperation the day before setting off for the Grand Canyon. Thank God. Not the greatest deals on the planet (everything was MSRP), but I felt relieved knowing that these guys were charging a FAIR price (albeit Nikon expensive) and that I wasn't supporting any sharks on the strip.
I was in and out. The gentleman who helped me out was kind and courteous. I have no comment in regards to their knowledge of gear since I didn't really ask 'em anything.
