Go 2 cycle! I got a Stihl this year, and WOW! It out cuts any electric I've ever been on, and is easy to start. Another advantage is that you grab it for a small 5 minute job with the same amount of work as it takes to get it down for a two hour job. That's one thing I dislike about the corded, all the time it takes to unwind before beginning and then to rewind when done. The extra cutting power and speed are a bonus!
