Entry level air fork suspension suggestions

[kovacsa]

Hi All, Can anyone suggest an entry level air fork to replace this one on my hybrid bike?

Suntour NRX D HLO. 63mm. Hydraulic Speed Lockout / Preload

I won't be doing anything extreme with it. I'd like to have a stiff adjustable suspension that will mostly be used for smoothing out the bumps on the road and gravel trails.

Thanks!
