Hi - I have a Pleasureway Excel TS and am very happy with my purchase. They are expensive, you are right but the downside is that they are very hard to find second hand. I looked for 2 years before I found mine. As I am getting ready to be retired and will be traveling solo with a dog, it was very important to me that I didn't have to haul, could park anywhere, a little better gas mileage and a quality build. The Pleasureway fit the bill and has served my purposes very well for 2 years. I have had nothing and I mean nothing go wrong with it during those 2 years. As for size, if you are traveling on your own, they are a perfect size. I have a medium size dog and I think we fit in just perfectly. I have traveled with a friend and I think for 2 people it would be less comfortable.
Hope you find what you are looking for,
