I am looking forward to handling a few of these now that Cabelas has opened two stores here in CO.
Here is my feeling on the matter.
Some have bashed the Sabatti from the get-go. Some deserved and a lot undeserved and it is common for some to say to save up for a Merkel, Chapuis, Krieghoff, etc (read "real double rifle") but I know that is not an option for most enthusiasts on a budget.

$3K is still $3K and nobody wants to get taken for three grand regardless of what their finances are. You can do a lot with $3K but really, that money doesn't go far in the custom rifle world and goes vitually nowhere in the double rifle world so the Sabatti is definitely filling a niche.
As for value, I expect full price Merkels, Chapuis etc. to lose more value (in dollars but maybe not percentage) than a Sabatti since the Sabatti is very near the bottom of the double rifle price range already.

In short, if you get one that shoots well for you, then I can't say it would be a bad deal at all. Who knows...maybe I will need one once I get a good look at them..
