I'm just wondering why, if the 346xp is so good (and I am sure it is), why is it so hard, maybe impossible, and confusing, to get a quality aftermarket P&C. I would think those companies would be falling over each other to get them on the market. I wouldn't mind upgrading my 2152 someday.
If you really want to upgrade, Buy Original Equipment, in this case.
For what it's worth, I like my 2152, just he way it is.
