CREECH is sort of a polarizing pin. Personaly, it is my favororite due in large part to the awesome, nostalgic, charming theme and top-notch artwork. Rules are criticized for simplicity, which is fair. I still feel like it is a blast every time and the multiball is unique and tense and very challenging with one of the best payoffs in pinball (ie. Super Jackpot with 4X playfield multiplier)
$4300 seems to be at the high end pricing-wise, at least in my neighborhood. But if it's mint with a good hologram, then it's probably better to strike while its hot, rather than delaying and seeing prices rise further, particularly if its local and you can play it.
good luck. CREECH RULES!
