Have you seen the Classifieds HERE? Some pretty yummy stuff is listed there.
I'd recommend you check for upcoming rallies in your area - WBCCI as well as Forum rallies. It's your best way to find the layout that fits your personality. Also check your dealers - you may decide on a new or nearly new unit after you see what's out there. It's far better to actually get inside and walk around, see if you can fit thru the door to the bathroom, try the bed to see if it's big enough and you can get to the bathroom without awakening each other. Diagrams and floor plans won't tell you that you can't close the door to the crapper without cracking your kneecaps.
I've heard Airstream of Arkansas is one of the best in the country, and even if it's a long drive - I'd consider visiting if I were in your area. (Make it a weekend trip and take her out for a nice candlelit dinner with wine and violins if you really want her to think that having an Airstream will be romantic.
