Best threadmill machine recommendations for 15k-30k range

Hi I’m looking a good threadmill in Amazon I can see powermax as some good reviews also when calling offline companies I can see they priced like 55k or above but doesn’t have better specs in online when I ask,

Any better suggestions also tell me if anything to keep in mind when buying online

Aim is : width should be at least 400mm+ less than I think maybe less space .
