Buying first motorcycle. I need help.?

Hi and thanks. I'm 6'3"280 shoe size 10-11.5 depending on the maker. I've looked around at dealerships and online. I'm taking the Safety Course this summer. I would like to get a cruiser of some kind. I'm thinking about a used 05 Kawasaki Vulcan 800 or maybe a 06/07 Vulcan 900. Is there anything wrong with these choices? Is there something better out there?I don't really care for Hondas, but I'm fairly open to everything else. I really don't want to spend more than $8000 on the bike. And since it is my first bike I would like something mid sized on power, hence the 800 and 900 choices.I live in sunny So. Cal. (covina) and would mostly be using this bike to go back and forth to work (about 10 miles ea. way) and to family and friends houses from 5 miles to 100 miles and maybe a Vegas trip (250+ mi.) so it should be comfortable and good for the cruising town and the long haul on the highway.thanks for the advice~Cerberus
