Congratulations on losing it! Welcome to the club!
Seriously, though; welcome. We always appreciate new members, especially those who love our favorite little system. Just follow these guidelines, and you'll fit in fine:
1. Don't be a doochbag. Treat people with respect. (Unless they treat everyone else horribly, in which case all bets are off.)
2. Don't price gouge. Because the Turbo is a special system to us, we are somewhat sensitive to people, especially eBay sellers, who treat it as a way to make money.
3. You shall OBEY the PC Engine! (Obligatory forum in-joke reference.)
Enjoy your stay!
