I consider my Puma 25RS to be entry level, but it has been a good quality trailer. I got what I paid for, and got mine for a very good price.
I call it entry level because there are better constructed TTs out there. Just small things, like screws/glue compared to staples, curtains instead of blinds, a backsplash in the kitchen, a better converter, AGM batteries, thicker insulation, and so on. I'm just being realistic... One can buy a Kia and find it a good car, but it still isn't a Maybach by any means.
The ironic thing, one can't judge by rig. Take a class "B" for example. One that is average will run about $120,000. That can easily buy a big honking 5W, a used diesel pusher, a decent gasser (either "C" or "A"), and so on. So, the type "A" rig may be bigger... but the tiny Airstream being pulled by an Airstream Interstate might be worth twice as much.
