Yeah, I got that guy. I have a fair amount of money, but I'm hedging by only buying one or two life extending meals, and rounding it out with a snack from Meramon. And part of me kinda wants my digimon to die, because getting new little guys is half the fun.
I feel like I beat the main story one or two digimon earlier than they balanced the game for. Just the hint from you or (one of the other posters) that I should be grinding on high exp mobs instead of gyming sped that up alot. And I've since seen a guide for what digimon to fight at what levels, and I basically trial and errored my way to 80% of it.
