I recently went through a similar process. The only modern, full function pre with tubes I could afford was a used McIntosh C220. List is ~$4K, used prices run from $2000-$2800 depending on condition. If that is too rich for you, consider a used SS Parasound Halo P7. It is probably the most full-featured pre I've seen anywhere near the price (list is $2K). You should be able to get it inside your budget on the used or demo market. I haven't heard it myself, but Kal Rubinson of Stereophile reviewed it quite favorably.
As long as you are giving up tubes, you might be able to find a used SS McIntosh within your budget. Just make sure it has a remote (only newer models do). A good place to check for used McIntosh gear (aside from Audiogon, of course) is Audio Classics in Vestal, NY. I bought my C220 there and was very pleased with the transaction.
Other than that, check out Rotel, NAD maybe Arcam for other choices.
