845 tubes. New not old stock


My Triode Corp of Japan 845 amp will need new power tubes within the next year or so and I am curious which 845 tubes are being by used by others and how much they are liked. I currently have Psvane 845T, which sound good. These are the original version. I tried out a pair of Dragons which were not as lively as the Psvane 845T's. I am considering Psvane 845 Tii or the KR 845's. Are there any other new manufacturers making 845 tubes within the last 5 years? Unfortunately all of the NOS 845 tubes are out of my price range ($7500!). I would like to keep it under $800/matched pair. 
Thanks all

Thanks for the responses. 
My amp is autobias with bias pots so I may stuck with a typical 845 parameter tube.
The transformers are really beefy on this amp, so I will check out the differences and see if I can try the KR's.
Are the KR's  more like the 211 parameters, a half way between 211's and 845's or something entirely different?

The standard 845 filament current is 3.25 amps whereas the KR845 tube has a filament voltage of 1.0 amp
I bought Shuguang WE 845 tubes for my Cary 805 AE amps at $400 pair from China.  I am very satisfied with the sound compared to the stock tube from Cary. Much bigger sound stage and magical mid. I was also contemplating Psavane WE 805 which is very well reviewed and would cost ~$750.
Anyone try the Shuguang black bottles?

There are exactly 2 factories in the world that make 845s: Shuguang and KR.
