I am thinking of picking up a F90bt from ebay. Will I still have the Premier warranty?

No

Not through Premier. I bought one and they place says they will honor the warranty. You can also buy squaretrade warranty.

The person I bought from has like 10 years of good feedback on eBay. Just be careful. Anybody almost will replace a DOA unit. Other than that depending on who you buy from you might be on your on.

Thanks for the info, I may have to suck it up and purchase from an ebay seller that is in CA which means sales tax for me. However many people have purchased from them, and the warranty is decent.
