Chainsaw Repair

so i've seen these around and do remember seeing them back when they were being sold at various hardware stores. just had one come through here needing a fuel line and carb rebuild (sorry no pics) and thought to my self: 'i need one of these!" i really have no use for one, but hey, it's gas powered and it cuts stuff. the guy said he loved it. uses it once or twice a year for camp fires and small pruning jobs around the house. aksed him if he remebered the price on it when it was new and he said around $250 or so. i've seen one (in toronto) on kijiji but that guy wanted $600 for a used one, and it was too far to pick it up even if i could talk him down to a more realistic amount. the guy was firm on the price and the ad expired.....
has anybody else run across these? have one? were there any other gas powered reciprocating saws? like i said, i don't need it, and it would probably sit around but just like a kid watching saturday morning commercials, i want one of them!
here's a pic off the interweb of it for reference:
