Chervon owns skil, skil now releasing 40v line with "battery cooling" technology. Maybe this line will be a more affordable EGO alternative from the same company in a round about way.
The hardest part in acquiring a tool line is the start up and appears that most of the cost is in the batteries and chargers. I am going to pick my spots for which to buy and what is required of the tool in order to complete tasks. I like the Ego products, having said that - they come with a price.
