Yeah, for those of you looking to buy a keyboard, I recommend searching around and finding a decent one rather than cheaping out on a crappy one. Keyboards are great because they're way more portable than pianos, but they can also be really low quality if you're not careful what you buy. I guess what you need to take into consideration is what you want to use it for. If you just want to play around and learn chords, maybe a cheap one would work for you. But if you're interested in learning to play well, or if you're going to use it to make recordings or play for other people, here are some things to take into consideration:

First is sound. Does your keyboard have a good range of different sounds it can simulate? How authentic are those sounds? Does is simulate a real instrument, or does it sound crappy and synthetic?

Next is size. I highly recommend having a full size keyboard. Mid-range keys are ok, but having those extra low and high notes gives you so much more scope to play around (and if you ever play any FF music, you'll learn that Nobuo Uematsu makes quite a lot of use of those low and high ranges). This is probably less important though than some of the other considerations. The advantage of smaller keyboards is that they are lighter and more portable.

Weighted keys: Ok, so this is maybe a frivolous add-on, but playing a keyboard that actually feels more like a piano is so much better. The biggest advantage of this is that the harder you press the keys, the louder sound you can produce, so you have a much greater range of expression. I love this so much, and I highly recommend it.

Compatibility and versatility: Can you hook up your keyboard to your computer? Can you make recordings on the actual keyboard? Does it allow you to lay down a track and put in different instruments? Does it require any special software? These things are good to know if you want to make any recordings or compositions.

Good luck with keyboard hunting!
