Watch for demo tours, I know Specialized and Trek are here regularly. Are there other shops that rent bikes? I was fortunate that my LBS does and had a full suspension (actually more than one type) in small, no prejudice against the short crowd there! What about driving to another bike crazed city (do you know someone with knowledge of Boulder)?
My LBS also ordered a bike without down payment and no obligation but we are very regular customers. Lucky for them I loved the bike, most here do require payment up front but some will not require you to buy but do charge a restocking fee. It is frustrating because I understand in my case I was looking at bikes with a $2500-ish price tag and those don't fly off the shelf in 15.5-16" but dang it I don't know what I want by reading a spec sheet!
Irulan is wise, patience is best. I rushed into my road bike and it isn't the perfect bike.
Took quite a bit longer on my mountain bike and it is exactly everything I wanted. It fits and rides like a dream but it killed me to have to search so long and hard.
