The Wellbrook is great, but not a big seller, especially the ALA 100,
which is just the amp. Based on serial numbers, they sold 3 in 9 months
in the US market. Other than size, the wellbrook beats out any of those
loops like the Kiwa or Quantum. The Kiwa might be of some advantage if
you don't have narrow band filters in you radio, but anyone forking out
the $400 for a Kiwa probably has a decent rig.

I suspect the US market doesn't like the hoops you need to go through
to buy the Wellbrook. No secure internet website for instance. No toll
free numbers.
