Can they go to the store and try out the pins?
IMO, for beginners and family, theme matters and access to multiball matters.
I would recommend T2 over Getaway because MB is easier to start. Getting the SJ remains challenging which is also good.
So if the family has a strong prefernce on theme, then go that way. If not, I think they can have more fun on T2. Starting multiball on Getaway is more difficult with having to hit the standups and lock the balls.
That said, both are great fun, great value pins. I think T2 should be around $2k in good cosmetic, 100% working, shopped condition. Getaway maybe a little more.
Also, if you buy from a vendor that backs their pins with a decent warranty service period, that's worth some money for non-pinball families.
