If you are set on latex, go HP, there is no other option, mamiki latex is pretty much non existent, so parts and service would be hard to get.
But if you are not sold on latex, take a look at some of the eco solvent machines, we got a new Roland VG 640 about 6 months ago and it has been pretty awesome, the colours with the new tru vis ink are very vibrant, I haven't noticed any smell, and prints are ready to laminate after an hour, also I only need 1 standard 110 volt outlet instead of 2 dedicated 220v outlets.
