And it was great.

Dh, however, would like to get a brand that is more easily available locally ( stihl, husqvarna) but works as well.

Around $300 max.

Here is what we need and it will get a lot of use, almost commercially, as we own many rentals but will also use it at our house. ( I will use it)

Very powerful, must cut a trench when used sideways. I use this feature for outlining beds.

Single shaft

reasonably lightweight

brush cutter attachments and possible edge attachment

gas powered with gas that has oil in it. Sorry, I don't know what you call that! Dh mixes the gas in a special gas can.

bump out cord or extremely long lasting string that doesn't have to be refilled until it runs out.

I am trying to do the research for this so if you can help at all I'd appreciate it.
