I don't understand what you are asking for... You seem to pose a lot of contradicting things here.
Are you looking for Ti or steel? You ask for modern steel in your 2nd paragraph, but talk about Ti everywhere else. A custom Ti will cost you some coin. You could get an older Merlin made from Master Kellogg for about 1K. If it fits you, you probably won't find a better frame (unless you get a custom Kellogg).
Custom or not? $2K is approaching custom territory for steel. A custom builder can make a bike that will fit your "classic geometry" requirements. Is it worth it? Well, I think I would definitely benefit from a custom. I think a Strada Bianca from Hampsten will silence the competition.
What will you be using this for? That will answer your question about modern vs classic. I think modern steel blows vintage steel out of the water, but that's just me. The best value for production steel bikes are the Gunnars made from OX Platinum. They don't come stock with level tubes, but you can request it. I have a Gunnar Sport and compared to vintage sport tourers like some treks I have ridden, they are lighter, stifffer, and more lively... not lugged though!
