Funny, I had an MDS .61 and ran it for three years at least 20 times a month. The only problem I ever had was the carb seal would sometimes leak. Just prior to the 3-year warranty expiring I sent it back to Horizon for repair and lo and behold they had replaced it with the .68 and didn't have any spare parts. So I received a brand new .68 in its place.

That certainly is not terrible.

But the OS 32SX was a different story
