Yes indeed, $ 99 for a single RFT EL11 is absurd, specially when NOS Valvos appear regularly at about $ 90 or so for a pair. I think prices of RFTs will go way down as soon as a new batch appears...as far as I know RFT produced a lot of EL11s, under their own brand and later mostly for Telefunken (and maybe also for Siemens and Valvo, who knows ?) after TFK ceased producing this line (in the late sixties ?) For example, it is well known that all Siemens branded EL34s, and a lot of TFKs of this and other types were in fact made by RFT in East Germany.
I first learned about the sound quality of RFT tubes with the EL12N, an excellent power in Euforia. Later on, I needed an “ultra neutral” driver to balance the warmth of the EL38s in my power amp, and while the famous TFKs and Siemens ECC81 more or less did the job, the cheap (and strongly built) RFTs ECC81 were a revelation in terms of transparency and sonic accuracy...precisely controlling the exhuberance (and specially the bass) of the “wild horses” as I call the 38s as powers. Anyway, the RFT EL11s are great drivers in Euforia, but not at that ridiculous prices !
