I've been trying to find some website but i could only find a few. Are there any below 150 pounds? Any suggestions?
Anything from WatDon gets the thumbs up from me - try and get the Challenger with the clutch if you can.
one last question... what's the difference between A062 Pro's Pro Challenger 2 and A07 Pro's Pro Shuttle Express (table-top)?
The main differences are that the A07 has a crank system and the A062 has fixed clamps. The A062 should give you more consistent and accurate tension results.
I wouldn't go near anything without fixed clamps, so I agree with @yan and push the 062 - the drop-weight is closer to constant pull than the crank as well.
