I've never seen one up here but in the states I saw a couple for sale in the last two years. Lowest price I saw was $1395 for a used but excellent cond. with extra mags for both calibres (that was 1.5 yr ago). Another one for sale about two years ago on Calguns.net, the owner wanted a straight trade for a Springfield TRP Operator or full rail Operator, he finally sold it for $1500 two months after his initial post...
They are scarce up here but since the collector market is light years behind what we see south of the border, and the asking prices of collector pieces up here reflects that too, I would say $1500 would be a tad on the hi side but if the gun is like described (near new), complete with the original box, outersleeve, papers and acc. it would not be out of line. I would probably buy this package myself at $1300-$1400. JMHO
