It's a bit of a haul from Reading (hour and a half....ish), but I could conceivably show up for a session once in a while, not every month though. What BT era are you considering (tech level, rules, etc.), and where would this be held? I've accumulate a "reasonably large" collection of older minis over the years (I've seen "unreasonably large" collections of more than 500 minis), but it's almost all 3025-3050, with maybe a handful of pieces from 3055-3060.
Started playing before the introduction of the Clans, and the local BT game group folded a couple of years after. Over the last few years, I've mainly just played at game conventions and an occasional MegaMek battle versus the 'bot.
