Original Vandersteen Model 3

I have a chance to acquire an old Vandy 3 pair for $400-500.  I haven't had a chance to listen to them yet.  I have a set of Maggie 1.7 with nice electronics, just looking to add a little spice to my life with a box speaker.  Looking for opinions on these speakers as compared to applying the same $400-500 to something else in the used market - floor stander or monitor.   Would it be worth my time to follow up on these?  Thanks
