Rslogix 500 license needed

I'm looking for the cheapest way to get an Rslogix 500 license for an SLC 500 (starter version). If you know anyone with a copy they would like to sell or if you know of a place that sells it at less than the MSRP of $610, i would appreciate it.

If you've got the software and are only after a licence, look into using RSRepair and then moving the activation.... Not much else out there will be cheaper than $0.
