Bob, seriously look for an older (1970s even) Ariens with cast iron gear box. 24" 7hp minimum, electric start and chains are nice options and can be added.... Mine is a beast. Was repowered before I bought it. Paid 400.00 Worth every cent. You do not want the model with the auger down on the body though... here is a link to one the same as mine, but no electric start nor repowered. Don't be afraid of its appearance.
