This sums up the negative vibes:
1. Consider a Tikka instead: less expensive, better scope mounting system, stiffer action, same/better accuracy
2. Beretta support sucks
3. A Tikka is a noticeably lighter rifle to carry in the field
4. Scope mounting options are extremely limited for the Sako
5. Sako's tapered dovetail mounting scheme is a PIA
6. Some of the larger (above XS) action sizes have ejection issues
7. COAL can be restricted by the proprietary DBM
8. There is no aftermarket bottom metal available
9. Aftermarket stocks are very limited
10. The lug/block action to stock design is not appealing to some
