Advice for New Player

[Foolsgold]

I primarily play SPww2 or MBT and I am looking to branch out into another game. I've decided it's either one of the Combat Mission games or one of the Tiller games. I played Fulda '85 several years ago and enjoyed it. If I were to purchase a Tiller game which one would be a good 1st choice in terms of finding opponents some of them seem pretty esoteric and can't see too many people owning them.

Looking at the forum at the moment it seems the East Prussia title is popular and that sounds very interesting. Could anyone recommend any other titles particularly WW2 titles that have a good player base?
