Need a scale that can tell the weight of my cars, don't want to spend 129 on the Sky RC scale. Any suggestions?

Try food scales. There are many options that are fairly inexpensive that should be a good start.

you just want a scale to weigh the car or one that reads corner weights? i got 3 regular digital scales if you or anyone else may be interested. pm me for more info.

Just the weight of the whole car

Not sure what qualifies as inexpensive for you, but this one will handle up to 6.6 lbs/3 kg. It use it to weigh my 1/10 stuff. A 1/8 car will probably be just a bit too much for it.

Standard kitchen scales go up to 5kg with 1 gram steps. You can get them for 10 up to 20 bucks.

I bought one off eBay for about $12. It's not just good, it's good enough. Hahaha
Seriously your going to get what you pay for.
