I have essentially the same mower already, but the Craftsman version. I've had it 9 years and it's held up well enough, although mine too has wheel issues. I don't mind buying it again, especially for less than I paid the first time ($300 or so in 2003 dollars). Just wondering if I can get something as good or better for less.
The yellow and black color scheme also makes it one of the ugliest mower I've ever seen, although I guess that shouldn't be a factor.
