Since you're still glimmering, it sounds like time is on your side.
I would highly recommend that you see all your prospects in person before making a decision. We walked through Tabs, Scamps and Casitas before ordering and I'm glad we did so. For me, molded fiberglass was clearly superior to stick built construction so that ruled Tabs out. After seeing a Scamp and Casita
we decided the Casita was the better option for us even though Scamp is in our back yard (MN).
Scamp, Casita and Escape
all make a good product and it's more a matter of personal preference, budget and availability on which is best for you.
Search the forums and do your research. It's time well spent.
