I need a meat scale that is accurate and interfaces 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 my network either via a wireless card or Cat 5 (LAN) cable. 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.
