I ordered a LH CZ 457 in .22 WMR right after I saw the original post.
It was no longer in stock at Classic Firearms. After quite a search I found one on Gunbroker. After I pay the FFL dealer handling the transaction on this end, my cost for the rifle will be a few cents less than $649.
FedEx tracking shows delivery tomorrow (7/8).
