I play several different styles and used to have a job that accomodated frequent GAS attacks. So, before joining the ranks of the starving self-employed, I accumulated this assortment:

Santa Cruz OMPW - my favorite for fingerpicking
Martin DC-28 - cutaway version of the D-28
Martin 00-15 - "my wife's guitar", this is the one that stays "at the ready" on a stand
Martin J12-15 - 12-string, stays in open C tuning - my retirement present
Gibson J-45 - my favorite for sessions because the shorter scale length=fewer broken strings
'60s Gibson archtop - don't know the model number - just for playing swing
Guild JF30 12-string - just a big old jangly Guild 12
Wechter Pathmaker Elite - double-cutaway, stays tuned CGCGCG, sort of a 6-string bouzouki
LoPrinzi mahogany D - my only guitar for years, needs some TLC
Alvarez 5080 Classical - for when the urge to play nylon strikes
Dean resonator - a cheap substitute for a real Dobro
Yamaha SA800 - ES-335 copy, for when the urge to plug in yet remain civil strikes
Fender Standard Stratocaster - for when the urge to plug in and get weird strikes
