but then again 380us$ isnt that much for what so far look like a true pro landscape app thats in my eyes looking like a seriously big improvement over whats currently being offered and it is a 200us$ discount, i realy feel its a fair upgrade price for v4 esprit users, just my opinion. Of course i woudnt mind it if e.on gave everyone a early extra discount to upgrade :) its of course alot of money, but you could settle for v5 + two of those modules. disclaimer: im not 100% sure what the v4e to v5i price was cant remember it so it could be more.
