[Trisquel-users] Anyone knows about a good POS seller Gnu/Linux ?

[aliasbody]

Hello everyone,

So I have to deal with a new law that passed in Portugal a few months ago,  
saying that every enterprise that sells directly to the client needs to have  
a POS (Point-of-Sale) with certified software (like it is the case with my  
Mothers bar).

The problem is that POS are quite expensive, and they are (almost always)  
pre-installed with Windows. I asked if I could do it myself (the software and  
the montage), but I can't since my software would not be certified by the  
Nacional Finances, and it costs a lot to do it.

So my question is, does anyone knows a reseller of POS in Europe (or even  
just the touch screen and the printer, I could use one of my computers).

Thanks in Advance.
