New scale suggestions?

My current scale stretches out at about 2 feet or maybe even 2 1/2 feet long at 115# or so, which is aggravating when trying to weight a bow on my tiller tree setup. The one part is starting to go to one side when I pull it too, it is hard to explain, but it is starting to scare me. It is one of those hanging scales from tractor supply company. Anybody know a better scale that won't stretch as much when you are using it?

Any digital scale.

X-SPOT digitals have made 75-80 bows for me and flew across my shop twice. Still tickin'.

Mines an old spring scale goes up to 150 pounds its older than me but gets the job done you coul maybe pick one up at an antique shop or maybe eBay

This guy looks cheap:

But this guy wouldn't stretch, where I am guessing the other one would?:

There is also this one for a little less:

What do you guys think? I want a mechanical one that will not stretch that much, if there is such a thing, but I am not sure where to look. The ones from tractor supply stretch too much for my current tiller setup. Pearl, I looked at that one, but it seems to only go up to 100#, and I need at least 150#, 200# max to feel safe using it often, ya know.

EDIT: I honestly don't want a digital one though because I am afraid the darn thing is gonna stop working on me or something. I would trust a mechanical one to last longer really. And I think one with a big dial would be easier to read when stepping back and drawing the pulley string to draw the bow, than trying to see what the little numbers say in the digital one...
