A good company that makes scales is one called Ohaus. Ohaus makes scales for both persoanl and industrial use. I bought a brand new digital scale (their HP-320 model) and retail I think it goes for $160. I bought it on eBay for $76 (and that included S&H)

It all depends on what you want to spend. The Ohaus I got weighs up to 300 grams but it measures in g, oz, dwt, ozt. Lots of digital scales only read grams or ounces, mine does both which is a nice feature.

If you don't want to go the digital route, you can get a beam scale. It's the kind they use in high schools. It has a pan on one end and a counter weight on the other. The work great too but they're harder to conceal because of their size.

Go to ebay and do a search for "digital scales" or "beam scale". You'll get an idea of what they're like.

Don't bother with a post office, hand held measuring scale, they're garbage and they're not accurate.

Hope this helps
