If that's your price range, there's other options. Look into some NOS E188CC's or 7308's(heerlen is my preference). . There's some excellent deals on ebay to be had. You just have to be patient. Also PM @rb2013. He has some excellent sounding Russian tubes in your range as well.
As far as the tubes mentioned. I really don't know much about them , and haven't seen any mention of them.
I'm sure others will chime in on NOS tubes.
Cheers
