About three years ago I bought a digital postage scale on Ebay - cost me less than $30 and it has been extremely handy. It's a DigiWeigh brand, made in China, but it's accurate and has a scale area about 6" x 10". (Note: when I tried going to their website Digiweighusa.com, I got a Google warning that the site might harm my computer.) It has quite a lot of capacity - I've weighed objects up to 60 pounds on it, and it's accurate to within an ounce.
The picture in this auction shows the exact scale I have:

Evidently this is a standard brand that makes a bunch of different scales. I searched Ebay and found a number of Digiweigh scales, including at least one postage scale that's currently at $24.99 and has a 76 pound capacity. Due to my positive experience with this brand, I think it's worth considering.
A digital scale is better if it has these helpful features:
- You should have a TARE function: this allows you to zero it with weight already on the scale (perhaps packaging), so that you can add weight and get an accurate reading.
- You should be able to press a HOLD button and hold the reading in case the object you're weighing blocks your view of the readout.
You don't need anything very big - look for a digital scale that has enough surface area that you can stand the end of a bass on it. You'll also find it's handy for postage and for Ebay sales if you're into that gig.
