Check on Racing Junk in the circle track equipment section.
There are usually a few sets of affordable scales there.
I have a set of Tanner scales I purchaced used from a fellow racer .....They split front and rear ond display percentages which does save some pencil and calculator time.
Usually the only thing you might find wrong with them are things like frayed or patched up cables.
Most of the good scale sets are pretty durable and made to take the abuse a circle racer might give them , IE multiple uses per week, dirt .
I know some guys who have had good luck with the Proform scales that Jegs sells .
They are way cheap, under $800 I think.
The RJ WeighRite scales are good also.
Mechanical beam scale platforms that use a heavy duty bathroom scale.
I had a set I had a set that I used for years with no problems , just a little more time to set up. ....Under $500 I think from Rick Jones Race Cars. ....
[ I just looked on the RJ website, looks like they dont offer the mechanical scales anymore.}
