Interesting ... the GB5 and the AV Linea have some relatively significant differences between them ...
Anyhoo, we are LM agents and have a linea and an FB-80 (internally a GB5) set up. Feel free to drop me a line.
Cheers,

PS. Im presuming that this is for a cafe, rather than for home use. If Im wrong, you might want to consider getting on the waiting list for the GS3 instead. Saw a preliminary price today and its actually a bit cheaper than I expected, although it will presumably be several months or more until any are actually manufactured and shipped here. Still, good things come to those who wait!
