Virtual Pinball is crap. No matter how good the simulation, its never even close
to the real deal.
I say, search for "Pinball Show", and check when and where it is. Take the trip,
and play away.
At the shows, you should be able to experience the gameplay of a good number of
pins. It will give you at least an idea of what you might like to purchase.... and in
fact, the pins at the show are usually for sale as well.
You might also join a Pinball Group... such as some listed on Yahoo Groups.
Some of them host regular pinball parties, where the host invites everyone in the
group to their basement full of pristine pins.
Still nothing?
Post in newsgroups and or Craigslist, that you are interested in playing some
real pins. Collectors are usually very happy to share the joy, and get others hooked
into the hobby.
Do Not buy a pinball blind. You may get a stinker... or a game that you will get
bored of in a week. A person I know dropped serious cash on a pinball she never
played... and is already trying to sell it after only a month... because its not very
fun for her. (AFM I believe)
You also want to look over a machine before sale if possible, OR get very detailed
and close up pictures of the machine. You want to make sure there is not serious
playfield damages, PCB hacks/battery acid damages, missing/busted assemblies,
serious errors, etc. Most things are fixable... but you should take all the fault into
consideration, as they reduce the value of a pin drastically. (FYI: European versions
of pins tend to be worth less here ((USA)) as they use different coin doors and some
altered wiring)
