I've had 928TAS for 3 seasons.  The only thing I've done so far is oil changes.  Once in the beginning of the season, and another at the end.
Good machine so far.

In your situation, one question I'd ask myself is, if the machine break/dies/etc., how much of a headache is it for me?  Can I still get in/out of your driveway?
Anyone else? 

In my case, if it snows more than 4", or gets iced over because I let the snow sit for a couple of warm days/cold nights, my entire family
needs to hike up and down 250' steep hill.  My parents visit often, and they wouldn't be able to even hike up icy/snowy hill.  So... I would bring
it and get it checked out.  Your situation may be different.

Enjoy your machine.

I don't have HS1132, but I've had HS928 for 3 seasons.  My driveway is long (250'+) and steep (~12%), not quite 2 car length wide.
Trackdrive is great, hydrostatic gear is even more awesome.  It can be a bear to turn it in tight corners, however.
Unless the area you clear is very straight and don't have tight corners, I'd get 928 instead.  Keep in mind that, even with trackdrive,
your machine can slip depending on the snow condition and the down/uphill direction, and you may have to give it more than a nudge.
My drive is curved as well, and I'm constantly steering it.  I'm never cold while blowing snow.  I actually sweat even in cold weather
(in New England).

Haven't had to use electric start, but I keep it in the garage.  I got it for peace of mind, and not regretting.  It's so expensive,
just another drop in the bucket.

Tell us more about the area you need to clear.  Commercial/residential, your location, steepness, length, width, etc.
