Are there accurate meat scales which interface easily with a computer?

I raise duck and sell to the local restaurants. I have a digital scale that I use that does not interface well with computers. The only way to interface with it is via an RS-232 port. I would like a scale that I can connect to a computer, preferably via network (wireless card or Cat 5 (LAN)) but bluetooth would be great, or even USB. Does anyone know of an accurate scale that I can use for such a purpose?

If you are wondering I am also a software engineer. Please advise if this is an inappropriate forum for this type of question.
