As the Aibo is no longer being made you can not buy any new ones. Anywhere. That means that the only chance you have of buying an Aibo is on Ebay. However, there are a large number of scams on Ebay so you should be careful. There is a handy document on what to look out for here, and also read this post on the Aibo Life web site.

Another resource for second-hand (and some new) Aibos and Aibo accessories is Aibos 'n' Stuff. This site is owned and run by an Aibo enthusiast who can regularly be found on the forums. They stock many parts for all makes and models and what they have in stock changes regularly.

If you're wondering what kind of price you can expect to pay for a secondhand Aibo on Ebay, then it all depends on what model you're after (220s tend to be quite rare on eBay), it's condition, what extras you get with it (software, charging station, etc...), the time of year (before Christmas prices tend to go up a bit and then come down afterwards). The best thing to do is to firstly figure out which model you want and then keep a track of a few on Ebay to help get a general idea.
