You could contact The Sound Room look into seeing how long from now the RTT MKL100 (going to be the "little-brother" of the MKL101) will come-out. I know it will go for no more than $1kUS once it does come-out though.

Oh, you might want to look into the the Microtech Gefell M990. I don't remember what it's going for but I don't this it's much over $1.kUS, regardless.

And IMHO of what others have said here:
I like the "A Series" of all the Groove Tube mics the most.
I not heard any of the CAD tube mics myself but I remember hearing good reports when the first 2 came-out, but obviously these A LOT more tube mics out now, so... I don't know the deal on those.
And YES INDEEDY did Ed put a smile on my face. The 797 Audio CR998 has been a "fabulous" mic for me! I 've been told the CR100 sounds JUST like the CR998 in cardioid but I don't really know for sure. A friend of mine has two CR100s so I hope to "test" that theory/rumor soon.

The thing is I'm sure if you can get a hold of them anymore. You can try contacting them and see. Another route to look at if you can't get a hold of them is the ADK A-51TC (EXACTLY the same mic as the CR100 but with a different finish and/or grill) going for $550Us @

Also, there's another route. It's
the Studio Projects T3 (which is suppose to be a "modified" version of the CR998) list-priced @ $1.1kUS.

And yet again, there's another route. It's the MXL V7 (EXACTLY the same mic as the CR100 and A-51TC but with a different finish and/or grill) which you can get for $575 @
