You don't say if you want a small one or a big one. If I ever decide to get a new small scale this is the one I think:

Prices are C$ so divide by about 1.4 to get US$. $50 Canadian isn't that much if it lasts -))

I've got a BIG old scale that I got from a food service supply place. The only thing in the whole place that wasn't at least 50% over priced. The scale I got can handle 30kg and was fairly reasonable in price. OTOH it's not the sort of thing you use to weigh 50 or 100 grams with.

So what I'm saying is a scale collection isn't a bad thing. A small fairly accurate one for small things. A big brute for those big heavy things that don't need supper accuracy.
