I am new to Warhammer 40k but not new to tabletops and I was wondering where is a good place to start? I got the Dark Vengeance box for this newest edition while at a game shop because of an anniversary celebration and I have not been able to paint any of the models since I am deep into Warmachine. I have gotten some free time and looked at the factions pretty much only in art and a little fluff since each codex runs $35-50. I don't know how the factions play out really and wanted some veteran players to give a rundown.
