Oh, Katisha. How did you know how many Wagner DVDs I own?? 
Katisha, I'd go for the Barenboim/Kupfer one from Bayreuth with John Tomlinson as Wotan ahead of the new Met one. The sets are a bit
, especially since Siegfried lives in a yellow and green nuclear submarine, but if you can withstand the post-nuclear stuff the singing, orchestra and acting are divine.
My other pick is a sentimental favourite - I love the old Chereau Centenary Ring, with Boulez. It was the first Ring I ever heard or saw, on battered old pirate VCR tapes. I went out the next day and sgned up for extra shifts at work so I could buy the Solti LPs.
Bryn is of course wonderful for the Met, and I ADORE Kaufmann
and very much like Westbroek, but I can't bear Deborah Voigt as Brunnhilde, and think Levine very so-so with the orchestra. (He's speeded up a bit, but not enough.)
You COULD also consider the Copenhagen Ring, though it wouldn't make for a very sane first choice. A slasher, dirt-horror Rheingold, telling and exceedingly grim. I also have a fondness for the Aix Walkure as a standalone, Rattle conducting and Willard White as Wotan...
And if you are in the mood for laughs, the OLD Met ring looks like a table gamer's wet-dream, as DS recently said. Styrofoam rocks and everyone costumed in Warhammer kit. Plenty of it can be found on YouTube, with the likes of poor Siegfried Jerusalem looking as if they have no idea why they are involved.
Now let's talk about recorded versions... Testament, or Decca?
