The two channel Brent Averill 312 unit is $1,679 including the power supply. An API A2D is $1,699 (but also includes 2 channel or A/D conversion). Two dual channel BAE's will run about $3,360. An API 3124 will run about $2,400. Their 500 series are both about $680 a piece I believe.
I have done records on both of them. I always seem to grab the API's. However, I don't think either one would be less suitable for the job. They are both great
