Query: Versitile & Reliable Trimmer/Addon System

I purchased the 720R 2 cycle trimmer 8 years ago and have collected many of the addon tools--blower, edger, vacuum, tiller,& hedge trimmer. I just replaced the power unit with the 890r. I really like the low emission rating and quiet operation of this unit. The great thing about it is that I didn't have to buy any of the attachments-the new unit uses the old attachments and they work as good as new. I have added the hedge trimmer to my collection and it works good also.
