Which Keyboard Should I Buy With The Mpc 2000xl Should I Buy An Mpd32 And A Keyboard Or Just An Mpk49 With Fruity Loops?

Should I buy an mpd32 and a keyboard or just an mpk49 with fruity loops? - which keyboard should i buy with the mpc 2000xl

I asked myself buying a mpd 32, so that you can use to try to drums and other musical instruments, buy a MIDI keyboard or separately, and also because of the purchase or Fruity Loops. I think in this way would be cheaper for me. If this is the best way forward?
Or
Do I have a MPK49 come with touch screens MPC (as MPD32) and also comes with a MIDI keyboard. http://www.zoom-in.com/media/graphics/bl ... This is a little over my budget, if = (

PS I can buy a premium http://media.zzounds.com/media/feed/larg Casio 61-Key Keyboard Bundle (CTK3000 PPK) ... MIDI-compatible and with reason or MPD32 and Fruity Loops Software?

In fact, my budget $ 450 =) is
Thank you!
