Don't throw away that busted Roomba! I will buy it from you. I can be contacted on Robot Reviews or at wynnyelle at yahoo dot com if you need to unload that Roomba you no longer want and want to negotiate a price. If you need proof of integrity I am also wynnyelle on Ebay, where I buy and sell these robot vacuums regularly.
I can pay by Paypal but understandably will not pay until Roomba is shipped.
Who knows? Once your roomba is safely here at "Robo-Haven" :P you may even see it featured on a blog post as "one of the gang."
