Which style should I buy?

Every person has their own opinions about which style is the "best". Rather than point out a definitive list, I'll list the pros and cons of each style, and let you decide. It is easier, however, to get the newer styles.

Pros

Huge songlist
Beginner friendly songs
Can be found cheap used
Actual music videos

Cons

Timing is bad on certain songs (gambol, overdoser).

Interface is widely considered to be poor compared to later titles

Which controller should I buy? I can't afford a controller right now, should I just play on a Dualshock?

Personally, I would wait to have the cash to buy one game and the controller at the same time. However, if you are -that- pressed for cash, I'm not stopping you from playing on a Dualshock. You won't get the same experience, however, and playing on a Dualshock is confusing as hell.

As far as buying controllers, there are a few options:

Konami Controller - An official controller by Konami, runs for about $90 from most online retailers. The keys are spaced correctly, but the turntable is smaller and closer to the keys. The keys are switchable so that you can emulate both the first and second player sides. People have problems with sticky keys, but you can mod your controller to get around these problems.

Rave Discman - Don't buy one. The price is attractive, but frankly, it's not all that great. For one, the keys are the wrong shape and are not spaced correctly. It's better to hold out for a Konami controller. It's possible to use a Rave Discman as a base for your own ASC, which some people on the forums have done. Take note this controller also has some voltage issues which could fry PS2->USB convertors that you might use.

Konami ASC - The official arcade-style controller by Konami. It's huge, it's pricey, and for some, it's worth it. The price tag is quite hefty, but with arcade perfect dimensions, clicking keys, and switchable from first player to 2nd player, lots of people have purchased them. Expect to pay around $450 when all is said and done.

Third-Party ASC - two controller makers well-known in the Pop'n Music community have both started producing ASC-like controllers for IIDX.

There's a port on the side of my beatmania IIDX controller and I can't fit my finger in there? What is it for?

The port is meant for a foot pedal for beatmania III, but no home versions of beatmania III have been made. You can plug in a pedal from the drummania home controller into it, and triggering the pedal acts as a scratch. Cool, but mostly pointless.
