We bought one for my brother last fall. He only climbs (not a bucket operator) and does 95% trimming (no removals). So, I thought for just over half the cost of a MS200T that it would be great for him. It weighs over a pound less (I think) and has more than enough power for trimming and smaller removals.
So, this spring I bugged my Dad to get me one. I do 50/50 on trimming and removals so I figured it would be great for me alongside my MS200T. My brother's has a 12" bar and mine came with a 14". The saw does not too bad in bigger soft wood as long as you take it easy. But it is definitely not a MS200T.
I enjoy the saw and will sometimes use it for bigger stuff just because it is lighter. I am not sure what bar you use but I would not go bigger than 14" and only use the chain that comes on it (don't go to the bigger chain like the MS200T). Keep it sharp and if you find it is not doing what you want save for a 200T and use the 192T as a backup/trim saw.
