Best Used Tube Based Preamp $2k Or Under?

As the title says, I am pondering my best options for purchasing a tube based preamp for $2k or under. Must have a remote! 

Your opinions, thoughts, and expertise would be greatly appreciated. If I was spending more, I would know most of the best choices, but I'm on unfamiliar ground at this price limit. But sometimes, you can only do what you can do. 

Thanks for any help.
