It's probably not going to make you a better photographer. But if you can afford it and a new camera will make you happy then go for it.
At my age all I have left is a big dick ...not photographic ability. Oh, and too much money.
Jim...we just passed by your area last month ....well at least on the other road north...318. I drive a Prius so wanted to test it against the road of the Silver State Classic. (They should be asceered.) Your way is longer from L.V. But I'd love to live where you do ...I love Nevada and love the desert. Those desert shots, and seascapes off cruiseships are what I do.
Next time we're down you way, Jan/2013, I'll come the long way and drop in. Ya got lots of Bourbon and loose women? Damn...I forgot, my wife will be along. So double the booze.. And triple the loose women.
Based on all the great advice here and too much money ...I've decided to get one. B & H? Or?
