Well considering you actually went to Bestbuy instead of looking on their website you're probably the type who wants to buy it at the store. If thats true, then checking the selection at the stores around you is all you can do. BB caries most of the units that are available so if you didn't see it there, its not really available or popular.
I'd say $210 is only on the edge of being worth it. But that comes down to your own value to a dollar. Its not overpriced by any means (disregarding that any and all headunits should be under $100 since they are not putting any real ground breaking or expensive technology into these things) relative to the market and other products.
If you're looking to spend that kind of money which you said you are, then yes, its worth it. It does what you want, and isn't a dud by any means other than the pico fuse issue. Here is what you would do to fix the issue which is generally caused by connecting or disconnecting RCA's when the unit is powered on. Makes it a pain when you're swapping things around but once its setup there is nothing else to worry about.
