Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

Hi,
I am looking to purchase a new snowblower in about a week, and have narrowed it down to these 3, though its not going to be an easy decision.    Any help would be greatly appreciated. 
The Ariens has the automatic differential which seems very nice, though it seems to have a different engine than the other 2 (not a Snowmax engine, I don't know what the difference is)? 
The Toro has a nice chute joystick and seems well balanced. No heated hand grips.  Do the wheel releases on the Toro or Simplicity have any chance of icing up?
 I like the Simplicity's strong frame, and the electric chute is nice too.  One wheel release vs Toro's 2?

Anything I should consider when looking at these 3? The 24" Simplicity also looked really nice, just from a smaller more manageable size point of view. 

Thanks

Well, I finally got to use my new toy last night.  We had about 6 inches of heavy heavy wet snow.  The snowblower through it pretty far, in some cases it looked like a big water gun the snow was so wet.  I am very happy (so is my back).  My wife was able to make a pass with it as well, so it looks like she will be able to use it in an emergency if I am not there! 

I sprayed everything down with corrosionx to help prevent rusting, though I would like to use something else (that stuff is expensive).  Anybody have any experience with PB Corrosion Stop, or recommend something else?

Thanks!
