[BC] Inexpensive exciter

[Tommy Gray]

I got a new BEXT the other day for 1400.  It was an unadvertized special.  Call them up.

I would look for a used QEI 675 or 695.  They're reliable, sound good and 
run 20 watts out.  They're also pretty cheap on the used market.

Also, PTEK sells a 5-30 watt  for $1,200.  Check 
http://www.ptekpower.com/new_page_2.htm .  I've never used one, so I can't 
speak from experience about them.
