i do have a 60" SW that I bought new in 86, I will never sell that cue-its family you understand.
I have a couple other 60" cues but nothing really forsale. My advice for you, and I consider this solid advice-if your going to play with it have the cue built for you. Pick a cue maker figure out what you want and build it-thats what I did with that SW. The reason I suggest this because there are not lots of 60" cues for sale. Or perhaps you want 60.5" or 59.5" or 59" when you build a cue to play with you can dial it in to what you want. If your looking for a cue to collect and use now and then; in that case shop around for something thats already to go.
thats how I see it, one disadvantage to that is when you have a cue made it might not play good when you get it, thats happened to me more than once. So if you find a used or new 60" cue you can test drive that's not a bad plan either. but I like the idea of building a cue the best.
let me know if I can help.
best
