]Well, there's nothing quite like a 175...there's a reason they're probably the most recorded "jazz guitar" in history.
EpiphoNE makes one now, that gets a heck of a lot of the vibe. Worth checking out.
Eastman makes the 371/2. People like them, but I don't think they sound much like a 175.
You might check the used market for "lawsuit" era Ibanezes and Grecos and such. Great guitars.
You can also find a Heritage 575 sub 2k used. They're not the same as a 175, but you can definitely pull a lot of 175-ish tones out of them.
I'm using a 575 here:
