I have tried the Horizon’s Quantum and they have good build quality and solid by looks.. But probably there are a lot of other better brands in the market.
u would need a 2hp motor minimum…ask for how long you can run it continuously and how long is the warranty for and what the warranty covers ..some people give labour warranty and wont give the motor warranty.. …above 100 kgs the treadmills go a little expensive because it has to support that weight,
the cheapest one would be a plain jane automatic, and the second one will have frills , the third one would have the auto incline …if you prepare to stress yourself then by all means go for the incline …
search for Afton …you would get that autoincline one @30K
