ATA advice needed

We are running an asterisk server and want to have people connect to it using an ATA.

I narrowed it down to Linksys SPA3102, Zoom 5801 and Grandstream Handytone 386/486.

These as most of the clients want to keep their POTS in the beginning.

What I got from searching is that the Linksys is good but is not sold anymore by Linksys but is still available. Zoom is nice but little community support, but Zoom seems to help. Grandstream looks/feels cheapy.

So I am leaning towards the Zoom, any advice or other ATA’s I should look at?

I am in love with Sipura for ATA’s.
