Best looking reel to reel

There's so many cool looking R2R, I especially like the vertical standing models. Revox PR99 MKII, Tascam BR-20, Technics RS-1500, Akai 747, Studer A807 and A810.
The reels and NAB adapters makes a big difference, these I call audio jewelry, up to you on how blingy you wanna get with these accessories.

IMO, the big Crown recorders with their large, black, bakelite knobs, are the quintessence of the art deco/industrial age.  Next, or on the same plane, would be the Studers and Ampex studio recorders.  If TEAC is your ideal, then maybe you don't want that look; you want TEAC/Akai/Technics/Sony.  Among the Japanese decks, Otari comes closest to the big three in appearance and perhaps in performance when properly tweaked, IMO. 

My vote would have to go to the one I had back in the late 70s, the Pioneer RT-707. It might not be the gnarliest, but it just may have been the most unusual looking.

I'm going to echo route-66 here a little. Pioneer made a higher end version of the 707 called the RT-909. If you're into chrome it should push all the right buttons.
