Hey Wisconsin,
Like you I would have to travel 2-3 hours to get to a bike shop with a really complete selection of bikes. I decided to go with the local bike shop and to buy my bike(s) where I would have them serviced, etc. For me it was a good decision because I get good service and good deals, the bike shop owners have become friends of mine, and I feel good about supporting my local community economy.
You shouldn't feel guilty about having the bike shop bring in a bike for you to try. It's all part of the business.
Also you don't need a big fancy computerized system in order to get a good bike fit. As long as they take their time and look at all of the different facets of the fitting process you can get an excellent bike fit with a plumb-bob, a tape measure, and a bit of patience!
Have fun when you get your new bike!!! Keep us posted.
