What is a reliable keyboard?

Hi! I'm looking for a keyboard that is able to register more than three key presses at a time, hopefully as many as possible. I hear that this problem is caused by the matrix underneath the keys not containing diodes and thereby not recognizing certain key combinations ( http://www.dribin.org/dave/keyboard/one_html/ ), but I can't seem to find any information on a keyboard that actually does have the diodes, which I guess would resolve the problem. My main use of this would be to play rhythm games such as O2jam, for example, or Stepmania, which require the use of entire rows of keys to be recognized independently from each other. Any personal recommendations would be great, or any information on what keyboards don't have the problem, since oddly enough nobody ever seems to market "number of simultaneous key presses" as a feature of a keyboard.

Thanks!

Are you saying it's more likely that USB keyboards will have a diode-laced detection matrix? Perhaps the protocol is better suited to sending mass up/down events, but I don't think that the keyboard merely being USB will allow this, since it is the actual physical construction of the keypad that matters...
 
Almost all Current Dome Membrane keyboards all have this issue I'm not aware of any that are not limited to 3-5 keys at once. Some older "clicky" keyboards (like the Ibm Model M) do not have this issue.
