I’m a Dyson fan. I’ll never get a Roomba because I love the power of my Dyson Animal. But the Roomba market on eBay is hard for me to ignore.
For example, based on October 2007 sales, the iRobot Roomba 530 has:
a sell through rate of 91%
an average end price of $233
a total monthly sales clip of over $31K
See the eBay sales stats.
Compare this to the iRobot Roomba 560:
a sell through rate of 66%
an average end price of $323
a total monthly sales clip of over $33K
These are great little markets. Any market with a success rate of over 60% is really good. I looked for big eBay sellers that specialize in the Roomba 530 market but I just found a few bronze level sellers, mybgis_1 and douglas33fl, who sell 3-6 a week.
Overall, the roomba market is $219K per month.

I would definitely recommend picking up a few of these Roomba 530s at the special Thanksgiving sales and list them on eBay for the Black Monday shoppers. Buy at $170 or below to make a $50 profit. List it as a 3 day auction with a start price of $19.99, a BIN of $249 and charge $15 to $20 for shipping.
