I know my mother in law bought one of the $99 bissells and it works ok, but it is smaller which means more trips to fill it up, more trips to empty, and more going over the carpet as it cleans a smaller area at a time. I have the bissell pro heat and it did run me almost $300 but my other large bissell that I had, lasted me 5 years so it breaks down to about $60/yr which is less than having your carpets cleaned once a year. I have huge dogs too and kids so my carpets get cleaned about once a month it's definately worth paying the extra in my opinion.
