I have the Almarro and you do not have to bias it every time it is used. I haven't biased mine in 3 years, I have even checked with my meter . Even the owners manual states when the tubes are new you may have some drift but further down the line it will stay put.
Almarro has a U.S. distributers so you do not have to worry about getting service.

I have even contacted them in Japan when I misplaced my manual and they copied to an email for me.
Love my Almarro
