I got the 4 barrel synthetic version about 4 years ago and its a class act.
Pro's: Quality, flexibility, trigger, accuracy is sharp and the dedicated scope is useful.
Con's: Price / after market options / Sako options (limited / pricey / and hard to obtain) and its not 'man size'!
I really like it, and love the ability to switch between .22LR / Mach 2 + .177HMR in a single shooting session.
But, I get a bit disappointed on the difficulty on getting accessories. Sako (Stoeger) don't seem very dealer friendly here in Van Isle, so I still cannot obtain something simple like the stock spacers. Also there is a small circle of specialist dealers who do accessories, most are US based, so there is always the import issue to over come.
Apart from that, its a class act, and my most versatile rifle. A really good fun to shoot. (I am getting addicted to Mach 2 for grouse hunting, like a laser over 125 meteres.)
