Currently it's cut down to a Martin D-18, an Iris OG (I think that's the model), and a Japanese Cortley Dove copy. All three of those are excellent. I have a japanese Hohner 710 jumbo.
The Japanese laminates are easily the best deal for the kind of money you pay, easily 95%+ tone-wise of their name brand brethren. I think she has $300 into the Cortley and I paid $350 for the Hohner. She had a Hohner HG-320 which is a D-41 copy and quite a nice guitar but she wasn't playing it and she even made a little money on that one.
If I tried to make a list of all the acoustics that have come and gone it would be incomplete, because I can't remember them all. Probably between 15-20 guitars in the last 15-20 years.
My personal favorite was my '63 Gibson LG-1 that I paid $150 for to a kid who wanted a Takamine, lol. Pure blues machine. Rang like a bell. Foolishly sold it to afford a 2k National Tricone, which I sold because it was too heavy and the nickel finish was a hassle to keep clean after playing. Her favorites are the D-18 and the Iris.
