I didn't find the 7900 all that durable when subjected to commercial use.and I am not talking about self inflicted damage.I really like hearing first hand experiences like this.
It is funny how by actually using a saw gives a different view then those that just look up specs.
When people go on about weight do they buy the lightest boots, clothes, helmet, chaps, tools belt, because clothes weigh a lot and you better only carry fiberglass handled tools no hickory handles.
Now back on topic hopefully by coming under one name it may open up easier and more budget friendly marketing.
Really no one really knows the long term durability of Dolmars because they are not used by pros by and large.
