If you had $2500 to spend on a new TT and cart.....what would you buy?

There are a number of very nice tables mentioned above that would make for a very nice and satisfying experience. Origins Live definitely gets my interest. The German manufacturer Clearaudio makes a nice entry level table the Concept that can be had with their (must have) upgraded Satisfy tonearm for $2,000 (same tonearm as on the Linn Majik). The Technics 1200GR is also a very nice table if I were to go the Direct Drive route. There are a lot of great carts for under $500. Music Direct has a good sampling in that price range. I have experienced the Hana Elliptical MC and the Ortofon 2M Bronze MM. Both are very nice carts for the money. 

@polkalover.. I recommended the Concept turntable and currently have one also but want to first say there are a lot of nice tables in your price range so do your homework and read as many professional reviews as you can. My budget was similar to yours and I would only recommend the table with one of the upgraded tonearms and not go with the standard tonearm offering based on my research and also based on a friend that has the Concept with the standard tonearm. The standard arm is much less user friendly when changing and setting up new cartridges in addition to playback quality.
I went with the Satisfy Carbon tonearm that is two upgrades up but they also have a Satisfy Black tonearm for less that is also a very nice tonearm. Upgrading the tonearm will cost you much less doing it at the time you purchase the table than if you decided to upgrade after the fact. The Music Room website has a good breakdown of upgrade pricing vs standalone tonearm pricing. 
Like I said do your homework as my experience with different tables is limited. I've owned Technics and Music Hall tables and thought they were great tables also. 
With that said I'm very happy with my Concept table so good luck with your search.
