I'm not a Ryobi fan, but I've had one of their units for 10 years and its still going strong. It has switchable attachments. Homelite makes a similar unit with attachments such as blowers, hedgers, etc. When my unit finally dies, I'll replace it with the smallest Echo. They make good, reliable tools.

I had a corded unit years ago and will never go back to one again. Cords are a trip hazard and if you have standing water, its never a good idea to use an electric tool, unless its battery powered.
