I have been a tabletop gamer on and off (mainly off these days, due to lack of time) for 30+ years. My only kit I have now is in 20mm using the 'Rapid Fire' rules Mark mentioned. When I wargamed in your scale back in the 1980s we used the rules by the Wargames Research Group.
I have some WW2 Wargaming links on my website at:

I would also recommend joining the Society of Twentieth Century Wargamers. They publish an excellent journal and have a website at:
