It is my understanding that 2005 is the last year for the LazerCT with the 44" deck. I think the smallest deck size in the 2006s is a 48", and it has the 18HP Vanguard on it. Many times, the Briggs engines get a bad rap on here because people are comparing the Mexico made engines. The commercial Vanguards are made in Japan and say so right on the block.
There's always the option of waiting for the Phazers, which I believe will be in a 34" and 44" deck option. Find the thread on New 06 Exmarks and see if it says anything in there about them.
Any rate, with the 44" CT being discontinued after the 2005 season, you can probably find some pretty good deals on them.
