What is a good barcode scanning system/software?

What is a good barcode scanning system/software?
I manage an audio/visual department for a big special events company. All we do is rent out equipment, and we need a good way to track inventory. We constantly have equipment going in and out, and it’s hard to keep track of it. Currently we use Synergy, but we need something easier and faster, and something that can work with a barcode reader.
