I'm a dealer for both and I wanted to get a 2147 so I looked into this myself. Tilton Equipment, which is the Jonsered importer for the US, makes the call on this. In their opinion, they don't feel that the sales would justify bringing it into this country. While it would certainly be a hit with the guys on the site, it wouldn't necessarily sell to the general public, who for the most part wouldn't understand it. This I think is the experience they had with the 2154/2155 years ago. Even thought it is the same as the 346, it would still have to go through the EPA certification process. And I don't think the 2147/346 generates the right kind of EPA credits anyway. It would be pointless to bring it in with a cat muffler like they did with the 2156. (The cat muffler on mine however, suffered an unexplained disapperance)
That all being said, I would still like to see it in my store, because I think I would be able to sell them (Plus, I want one for myself)
One other thing I'm not clear on is what the future of the 346/2147 chassis is. I think I saw some posts that it is due to be replaced. Sawtroll; you always know this stuff. What's up?
