they are nto hard at all to draw, in fact far easier to eliminate the grid. i <3 hex tiles and was thinking about a game based on them recently (actually 2, one an rpg/"pokemontype" game and the other an army strategy game)
just make sure that you get everything sorted out far in advance
also i would suggest using the "perfect" lines (1/2 slope), since an actual 30 degree angle will end up broken and ugly unless you work quite large
