Ahhhh! Well, a suggestion is to start looking NOW. Buy stuff NOW while you aren't under any pressure to get out there. I don't know which side you wish to do, but it cannot hurt to look over at:
If you are gonna do German, I can give you some advice.
As far as units go, no matter what, by all means, look around and check out the units. Some are quite "intense" some are laid-back. Read all their stuff. Go w/ your instincts--if a unit sounds to be un-fun or somethign you don't like... just say "thanks" and keep looking. If it ai't fun, why do it? Don't let ANYONE make you feel bad, small or like you're not wanted. There's way too much politics in reenacting, so just tak eyour time, don't get in a hurry and use this time to build up a first-class kit!
