Hi,

The Trig TT21 and TT21 are similarly priced (a little more expensive) but
has proven to be a fantastic product. Also, its control head fits into a 57
mm instrument hole, or a smaller hole.

It would be interesting to compare the current draw of the 2 brands. I'd be
surprised if the Sandia unit uses less power than the Trig TT21.

Best Regards,
