If you're going second-hand, though, an older Heritage II Legend or Legend II might be easier to use than a Generation series, and probably performs just as well for most purposes. Earlier ones are harder to get bags for, and/or use dump bags, which can be a pain - but the last two or three models prior to the G3 are, IMHO, the finest Kirbys ever made. (Not that the G-series is bad - it's not - it's just that the Legend series is less clunky.)
