I use an "American Weigh" scale that I got off eBay about a year ago. It was priced good and it weighs up to 50lbs in g's or oz's. I use it to weigh my shipments, my snakes, my chinchilla's, my guinea pig, etc. It's a great scale and I love it.

Here is the link to it:

You can find one on eBay for about $15 if you are lucky.
