i was looking today at buying a new blower. i've had and still use my eb430 for 6 years now. I was wondering if there is a major, noticable differenc in the 3 models...........4400....4800....7001. obviously, the 7001 is the strongest, but is it really worth the extra$$$. I was only able to get a price on the 4800 ($500). they were too busy to help me with anything else. Also, while you're here........ redmax strato 2400 or shindawa t231? aren't they very similar?
