For what it is worth, I will add that some folks spend so much time looking, that they shorten thier time to enjoy. Educate yourself as well as you can, do your homework, narrow your choices, have a survey done, and pull the trigger! Just remember that when you buy, you have to be thinking about selling, so be in it right, and don't get anything too "kinky".
I have a buddy that gets what I call "Paralysis through Analysis". whether it be a boat or a TV, he gets so buried in comparing and afraid that he is paying too much that he never does anything! When he misses a killer deal through this, he measures all other deals against the one that he missed. He usually just shakes his head at me as I will buy and sell more stuff in a few years, as he will in his lifetime. he sure likes riding in my stuff, though! (and that is perfectly fine)
