I bought a Platinum SHo with the LCT engine, havent used it yet, but seems to be decent, well thought out and starts easy.
Ariens makes good equipment, plus I bought it in early Oct so I got the 5yr warranty.
I have a 21 yr old Craftsman 30" with 10HP tucumseh, that thing is noisy and chows gas and does not like the ethanol. Just rebuilt the carb and fixed a few things on it and it is ready as backup. I have to get to work in morning and my neighbor and I kind of looked out for eac hother and if either had an issue with their snowblower would help each other, I bailed him out a few times when his wouldnt start and he bailed me out when I lunched a belt. But alas he moved so I have two blowers.
The new one is night and day better. Change the oil, throw a new plug at em and fix anything else and they will last a long time.
