wanting an rx8

I am new to this forum so please pardon any mistakes to this. I am looking to purchase an RX8 and am located in the Ogden, UT area. Because of my location their are very few 8's available for purchase and I am unable to find one I want. :banghead: Due to this I am contemplating purchasing one out of state via ebay, craigslist or some other website. So my question for all of you is what are your opinions? and does anyone have any experiences with purchasing out of state regarding sales taxes and everything. Also I would prefer an 8 that is NOT silver(gray) or red, with less then 50,000 miles and preferably a series 2 however my max price is 15k so I may be out of luck, I just don't want to purchase one that will need a new engine within a couple years. Thanks :)
