Before you automatically say the 7001, I want you to consider my question... I am trying to decide if I really need the world's most powerful BP blower haha (or close to it). I don't have to blow off any parking lots I only mow COMMERCIALLY during the summers. I am in school during the winter so if I do leaves it won't be like I'll have 20 accounts to keep up with (BUT I do want the ability to blow leaves well when winter comes so I can make extra money). I am about to purchase a blower, and am leaning toward the Redmax and Echo products (2 year warrenties - but Redmax may not have 2 year on the older model number 4800 lists as 1 year for some reason, I think it may be because the 5000 is the new one?). But considering I can escape with only about $300 loss getting an Echo 603 or Redmax 4800 is it really worth spending about $440ish to get a PB750/650 or a EBZ7001 blower? I really wish I could go demo some, but since I know I am not going to buy their product, I will not go demo them and waste their time and put wear on their stuff. Also, I use an Echo PB2100 blower now (now called the PB200), so I am not used to an amazingly powerful blower. I want it to be WAYYYYYYYYYYYYY more powerful than it though. I am so tired of spending 10 minutes blowing of all things. So basically if by only getting a 4800 or 603 I am going to see only minor improvements I need to go with a 750/650 or 7001, but if either are going to be far superior than I should go with a 4800 or 603. Sorry for ANOTHER long post, but I can't buy before I know what I'm doing.
