Which scanners do you recommend?

Hi all,
I hope this is not OT!

I recently introduced a new commercial av scanner on my systems in
additional to Clamv
and seems works

inside Amavis's config I see a lot of number of scanners template, but I
am not be able to test alll

I wish use scanners that

* works fine on Linux (Debian), possibly packaged
* easy to integrate with amavis
* a good quality / price ratio

In short: which scanner are you using

TIA
Alessandro
