Trygve;
I have a Nordic Trac incline trainer that I bought used for about $1000. It was the cheapest model that NT made at the time. All the NT incline trainers are pretty much the same. The higher the price, the bigger the screens and fancier electronics but the function is really the same It is fine for home use but is not particularly robust construction like a Woodway which is a professional lab grade incline trainer costing several thousand dollars.
The NT goes to 40% grade where the Woodway only goes to 30% I think. These are the only two brands I am familiar with and I am not even sure there are other brands. If I had it to do over again I would have stepped up for the Woodway. The NT is kind of a flimsy POS. It will get the job done but has some problems.
The speed of the belt is not constant. This means that somedays 5mph is not the same as other days at 5mph. That’t not huge deal unless you want to compare workout to workout. The angle of incline is grossly inaccurate so I have to measure with an inclinometer and adjust so that if I want to be at 30% I am actually at 30%.
All that said It is still a very effective training tool for bad weather or smoke. And you can vary the grade so that it has some running and some hiking. even downhill because the NT will go to -10% grade. For longer workout i watch movies or listen to podcasts.
If you do not live close to steep trails this thing will really help you. Just don’t expect high quality from the NT.
