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

I'm sure this has been answered many times already but I'll ask again.  I have a toro 826 dual stage snowblower and would like to add a single stage toro.  One of our local dealers is having a sale on these units.  He has a bunch of toro 221Q and 221QE models from 2009 and 2010.  He also has several 621 versions from last year left over.  Price wise, the 621 are about $25 more.   The 621 does seem to be quite a bit larger than the 221 in frame size.  The questions I have would be:
1. 2 stroke or 4 stroke?
2. Electric start or not?

Thanks in advance for any responses.

Thank you to all who replied.  I went with your advice and bought the toro 221QZE with quick shoot and electric start for $749 Canadian.  The electric start was $100 extra but hopefully it will be worth it.  Gotta wait a while for the snow but the combination of my toro 826 dual stage and the this single stage snowblower should be fun to use.   The snowblower came only with one key?  Was there supposed to be a 2nd set?

I received one key with the Toro.  The Honda 2-stage came with two keys.
