Which 150 would you choose ?

Don't be a damned fool. Go with the Yamaha. Find an authorized Yamaha repair shop in your area that is not an authorized Yamaha dealer. Have Eds ship it to them for installation. That way you will have the full Yamaha factory warranty. Don't try to have it shipped to an authorized Yamaha dealer because he will want to kick your ***. ;) Consider buying the extended warranty while you are at it. Hope this helps.
