Guil,
VDO makes some nice 2" gages in this price range. They are used in multiple
applications, not just aircraft. They are called the cockpit series.
Hope this helps!

Subject: Re: Europa-List: EIS panel suggestions
Ive been looking at some EIS systems myself, and looking for guages to go
along
as backups.
Can someone recommend good low-priced guages? $35 a pop sounds pretty good,
but
i havent found anything like that...
thx,
