I know this question has probably been asked a thousand one times, but what do some of the old salts recommend for a good starter set that won't be overly daunting to a newbie, but still has the potential for expansion down the road? I see 4'x8' being thrown around alot, but I don't want to get in too far over my head. I'll be working in HO scale, because I'd be afraid of breaking the N scale trains. Hehe. Thanks in advance.
