Before you venture off into NOS tubes, which addmittedly can be better in many applications, try some of the alternative new production 6922/6dj8's, and see what you think of them. Try the EH, also the JJ, which sound nothing alike, and given your financial considerations and lack of real focus, may just float your boat. If you don't like either of these tubes at least you will have gained another reference when asking for advise, for example my observations of the performance of the EH. BTW the EH is not a 'bad tube' at all. Lots of folks like it!
Caveat 6922/6dj8's that are quiet and worthwhile are usually very expensive. I prefer Amperex BugleBoys, some Siemans, and Tele's. Old Yugo's (EI's) now hard to find, are probably my all around favorite. Be very careful about who you buy from, this is classic swampland territory.
