What model should I get?

The model you should get really depends on what you want and what you can afford. ERS-210s were the best selling and therefore they are typically the cheapest, however they are also prone to more problems when left unrepaired. The ERS-7 is the most advanced and has less problems, however it is also the most expensive. This section should help you decide.

Buying my AIBO

You should be cautious with where you get your AIBO. You can get it cheap from Japan, however shipping and customs fees will cost a lot, and you might not be able to communicate with the seller if the AIBO doesn't arrive or work. You may think buying it on eBay is a better option, however there are unfortantly a lot of scammers on eBay. Here are places you could buy your AIBO from:

Import it from Japan

It is possible to import your AIBO from Japan. AIBOs in Japan often sell for less than AIBOs in the rest of the world. A popular place to import AIBOs is Zenmarket. Zenmarket is a Yahoo Japan proxy that will buy an item of your choice and ship it to you. Japanese AIBOs that are untested or not working are marked as JUNK.

Buy it on eBay

Many people buy their AIBO on eBay. eBay is often a great place to get a cheap AIBO, however there is also a lot of shady sellers and overpriced AIBOs on eBay. Make sure that the AIBO you want to buy doesn't have any of the red flags mentioned later on in this webpage.

Buy it from someone in the community

People in the AIBO community are often selling their AIBO, whether for financial reasons, wanting to clear space, or just simply not needing them. Buying an AIBO from the community is considered the safest option, as AIBO forums and chatrooms are fully moderated. Popular AIBO forums and chatrooms include AIBO-Life, Aibo Connect and Robotchat. All of these places have specific subfourms or channels to discuss buying and selling AIBOs.

When buying your AIBO, you should avoid sellers with poor ratings, AIBOs priced significantly more or less than the typical selling price or AIBOs from sellers that are no longer considered trustworthy in the community. Untrustworthy sellers include:

  • Yaba (aibodoctor.com) - has scammed buyers many times, claims to sell repaired AIBOs which brake quickly, faulty repairs, stealing images from other sources
  • Nippondeals - has scammed buyers many times, claims to sell DHS-free AIBOs which brake quickly, faulty repiars, overpriced items

You may check the images of your AIBO on a reverse image search engine such as Tineye or Google Images to check if they appear anywhere else online. You may also keep an eye on the AIBO-Life forums.

Repairing AIBOs

Unfortantly, there are not a lot of repairspeople in the AIBO community today. Because of that, it is best you go with a model that has been fully tested by the seller. However, you may get your battery recelled by Bruce. Never, ever attempt repairs yourself without knowing what you're doing. This can be dangerous for you and the AIBO and can result in making the AIBO's problem worse than it was before.
