Go play them and buy 1 or 2 maybe 3 of the ones you like best and need the littlest work. Look at the 3 aa batteries in back box for leakage probably don't want board repairs to start. To me judge dread and tales are $2000 each when working. Jurassic for $1000 sounds good unless totally beat. The other 4 I would pass on unless a lot cheaper.
