Personally, I'd look for an old Marantz receiver with the thumbwheel, it has the combo of being both a great performer and also a great looking design. For a consumer reel to reel, the Technics with the Single Capstan loop is a really great design. At work I also used professional RTR's like Studer-Revox and Nagra, and if you could find a deal on one of those they would be nice.
Even back in the day RTR was cumbersome and required a lot of space & gear - but there is no denying the mechanical beauty of the machines and the excellent sound of a good 15ips recording.
