I do not have any experience with the saw but a little information about it.

That saw engine is also sold as the MS192T model. The other model is a top handle saw used when climbing.

It is an okay saw as a climber, but no comparison to the MS200T.

It looks like the 192 has lightweight going for it. If I had to choose between the lightweight and horsepower, I think I would choose something with a little more horsepower, like the 180. I don't know the construction of the 192 compared to the 180, so the 192 might win on that aspect. But for light around the yard work, the 180 might be a better choice. I am not sure what the cost difference is but my guess is the 180 might be cheaper.
