BMTran,
Why don't you wait till the Tornado F6's come out, which, just like with any new adopted race car models and types, immediately obsoletes (not all of them) one or more of the previous models. There will always be people willing to ante up for the latest model, thus having to put their current one on the block.
If you enjoy the play of the standard Tornado, and do not need the current model to prepare, like those who tour more often generally like to do, you might see several more available coin-ops put on eBay and CraigsList after October.
The fact that these used Tornado coin-ops in good condition can last for decades with due care can really help your club or league or foos group.
