Why would you like to update the software?
I'm just thinking that if I buy a unit from eBay to retrofit, I'd want to get it up to the same software level as the rest of the car. I think I'm starting to understand how to do it myself (using WinKFP and the latest SP-Daten files from ISTA/P), so perhaps I'll try buying one and see how I get on. I just don't like the idea of paying one of the vendors £1k+ when I can buy the parts for £600 and an OPS head for £300 then do it myself...
