Unwanted ATAs, what brands?

I need a couple more ATAs for my asterisk. What brands should I search for on eBay or ??? that have low successful bids. i.e. have few wanters. Need to have an acceptable dial plan usage to work for use as extensions in *.

I have an Access AC-211 but have not figured out how to get universal passing. I have to code every size of string. Two more nicer ones would be better. I am looking for brands with low winning bids that will work fine for extensions. 8)

sipura/linksys ata’s are pretty good and are widely used in * systems. Make sure that you are getting unlocked units (ie PAP2-NA). the non -na pap2 is often locked to a service provider.

Alternatively try a digium TDMxx interface card…
