The saws that still bring the big smile to my face are my many 288XPs. I cut many thousands of trees with them over the last half of my felling career, everything from small lodgepole pines through Doug fir pumpkins. Imagine my surprise when I changed from Homelite 550s in 1980 to a Husqvarna 2100! Yikes, what a joy. I purposefully washed those Homeys at the car wash and neglected to start them to dry them out. I was particularly happy when they rusted tight. That meant I could buy more Huskys. I still fire a 288 when I've got to do serious felling or bucking, stuff over 40".
Of all the many Stihls I've run and also own, I'm most impressed by the 6 025s and MS 250s we use. Yes, they're consumer saws. No, they are not underachievers. We prefer them for the small arborist tasks we take on. They have been completely reliable for 10 years. We run 020/200ts up to an 066 and many pro saws in between.
