1 7 stringer, 1 six stringer (although I plan to get a 006 Hellraiser soon, so make that 2), and a 4 string bass.
Ah yes, I just realized this is my first post since... um, June 2006? I forget.
The only 6 string I've ever owned is a Squier strat I used when I first started playing guitar, and I don't even use it anymore. I now play 7 strings exclusively, even if I play songs that never use the low 7th string.
