This thread is funny, because I was just thinking about these books the other day! I was absolutely obsessed with BSC when I was a kid. I started reading when I was about seven or eight, and read them up until high school. I own maybe about 75% of the original books (none of the spin-off series). They're packed away somewhere in my storage unit. I doubt I'll ever give them away or sell them off, I actually would love to finish the collection just to have it, even if I never read them again.
