Killer vintage 70's, 80's reel to reel to add to my setup.

Any model Studer that has been properly reconditioned will probably cost more than your budget.  But, the same company made Revox machines that were intended to be non-studio machines that are nice and much cheaper.  Look for an A 700 or A77 or B77 machine.

Thank you @clio09 ​@larryi  I've gotten some great info to work with. 

Wow, prices for new modern decks are crazy expensive and not that great looking until you get to Mataxas & Sins Tourbillon. Now that’s a cool looking deck! And I thought my budget of $7500 would get me top of the line in the new deck area. Not even close! Vintage it is!

THE “new” machines that I like come from United Home Audio.  The top machine utilizes a reconditioned Tascam transport and electronics that are designed and built by them to be the very best; it better be good because it costs in excess of $90k.  You can hear their stuff at audio shows and at their DC-area showroom (very nice and friendly people).  

The Metaxas & Sins decks are based on the Stellavox SM8, arguably one of the best decks ever produced based on comments I have heard from a few recording engineers. I have the capability with that deck to use the internal electronics for playback, or take the signal direct from the tape head. In my comparison this is the only deck I have heard where the internal electronics stack up well with my tube tape head preamps.

If you're going vintage another consideration is to ensure it's serviceable and to have a good resource available to service it. With all due respect to @larryi the Revox A77 is one to stay away from. Revox makes fine decks but the B77 and PR99 are the ones to seek out. With any vintage deck, just make sure it has 15 ips tape speed, not all do.
