Newer Toro 521 vs older 35/4/5-21
I think I'd like to get a small 2-stage (to go with my HS621) for EOD and larger snow falls. I've seen a lot of good things about older 3521/421/521 blowers, but also seen newer 521s with pneumatic tires (that's the identifier I've noticed). Is there any significant reason to go for a newer 521? The older blowers seem to have a great following, and I'm not afraid of older models that might need some work. I wouldn't mind getting getting an older one (maybe a 3521) in worse shape and try repowering, but I don't know if the newer has some essential features I might want (is the pneumatic tire better?).
Also, if anyone has a rough timeline of the models, I'm curious what year range the newer 521s were made.
I did some parts searching, saw that it looks like the 521 was last made around 1996, and the 3521 was made back to 1989-1983, and the 421 was made in 83 and before.
