Yeah, factory tour looks like an interesting trip. Free Avatar toy: don't know why but it reminds me of the Jar Jar Binks toys from SWEP1 that MarkC is still trying to get rid of!
I have played LOTR and enjoyed it, to me it was a very good pin.
I have played POTC and enjoyed it more, probably the theme was more attractive. Ball times can be very long on both these machines.
Haven't had a chance to put any decent time into the newer titles but have had a quick bash on CSI, BBH and NBA and they seemed reasonable machines in the short time I had to assess them, with probably BBH the least engaging title theme-wise.
