Yes welcome to the board! All of the machines have their own particular charm. Must haves are Dependant on your own interests and personality. I've had a few must haves till I got them and then realized, well they really weren't must haves but not too Bard's.

Net manufacturers the real quality machines. IGT makes the most playable machines and Sammy makes the machines with the most squeal. Yamasa's tend to spin faster and reduce if not eliminate the concept of eye-shooting. There's a plethora to choose from and individual taste for the theme is of high importance.
