Will be demoing my own XT5 this fall! Actually looking forward to aerating season this year.
Got my XT5 last week, did a quick demo in my yard and it actually pulled some pretty decent plugs, considering the hard, dry clay soil we have. So far very impressed with the design and easy access to all the maintenance items. Doesn't seem to be top heavy as others suggested, but I have a couple of lawns with some pretty decent hills, so I'll follow up with that in a couple of months. The B&S engine is very quiet too and has plenty of power.
