Welcome to Pinside and welcome to the awesome hobby of pinball.
You have done the right thing in setting yourself a budget for your first pin and also playing machines within that budget so you can narrow down your target list. Funnily enough, when I first started looking for a machine, I went for a System 11 game and bought PinBot. That lasted a few years before it was sold to make way for an Attack From Mars Remake LE.
The Addams Family (TAF) is a sort after machine and demands top $$$. If you were to find one cheap, I would want to check it out to make sure it doesn’t end up costing you big dollars to fix it up etc. Best bet would be to take someone that knows what to check on machines so you can avoid expensive repairs before you even get to flip the game once.
Speaking from my own experience, start with the budget you have set yourself and aim for the machine on your list - they are all pretty great titles to get you started in owning a pinball machine (and of course, having heaps of fun).
