Be aware of vendors that offer longer warranties without covering the diode.  Because majority of the time the diode is the problem when your laser fails.
Be aware of vendors that offer 6 months or extended warranties. If you have been using EBAY for a while, you probably notice that after 60 days you will not be able to open a case here on EBAY. Then, you ask yourself how are you going to chase after these vendors for the extended warranties that they promised
