I think I'm going to go with the following:
Mic: Audio-Technica AT825 - Cardioid Stereo Condenser Microphone
Mount: AT8415 Low Profile Universal Shock Mount
Stand: Shure S15A - 15' Telescoping Microphone Stand
Cable Extender: Comprehensive Digital aes-ebu cbl - 25' (xlrm - xlrf)
How does that sound?
This would be $592.35 - $100 Gift Card that I have.
That's a pretty good low-budget mic for single-point recording, IMO.
Skip the Shure S15A stand - waaaaay overpriced, IMO. Bogen / Manfrotto makes a few of stands suitable for our purposes, for well under $100. Check out bhphotovideo.com for pricing and models.
Cable extender - is that to run from the mic to the recorder? If so, you want a mic cable, not a digital AES/EBU cable.
Also, what recording device do you plan on using?
