I know the 21 has been beat to death lately. I have 1000.00 to spend on a 21I will be using this on small high end residentials. Open to suggestions on ther brands but I have studied up on 2 in particular. The commercial toro recycler I can get a new left over 2006 new in box 799.00 + shipping. Or the Toro Super Recycler model 20057 for 609.00 free shipping. Will not be used 8 hrs a day but frequently. Great bagging and mulching are a must. Any info will be appreciated.
