I had a chance to handle a Sako Quad last week, though I wasnt able to shoot it. The rifle itself is very light weight and appears to be put together well....of course it's a Sako

The price for it was $760.00 with one barrel of your choice. As you probably already know the barrels are color coded to a caliber. The rifle I looked at was a 17 HMR and had a orange band on the chamber area. The salesman said Burris is making a scope especially for the Quad, it too has a color code that you dial in for the caliber of barrel you are using. All in all it's a pretty neat set up, it does seem that the market for it will be a small one though.
I wound up buying a Anschutz 1517 HB and a Ruger 77/17 that day and will have a post on them soon. They are both chambered in 17 HMR.
