I've been looking for ICs to do conversion and it's going to be about $20 or so. $15 if bought in lots of 25 or more. Might be cheaper ways to do it, but I think in the end we might be better off using readers that do native 485 when exceeding the 232 run length, or perhaps using a relay to extend the range, which shouldn't be too expensive.

Just ordered two samples of a MAX3162 (unfortunately it's only available as surface mount) which is a RS232/RS485 converter on a chip. I still think getting puropus built readers might be a good idea for quick deployment, this will allow for development of alternate options.
