8 mA is really a small current drain. Aside from the Audio Buddy, I
am a Denecke dealer and can sell you the PS-1A phantom power supply
for $118. See:
http://www.denecke.com/prod04.htm#PS1A
It will power your mike for a couple of days on a 9-Volt battery.

first off, you can connect a 9 v dc supply where 9 v
ac is required. you may in fact need more than 9 volts
- approximately 9 x 1.4 volts (which is what would be
happening if the 9 volt ac was rectified and smoothed
inside the audio buddy.
9 volt dc should cause absolutely no harm.
