Whatup CaptainCommando,
I'm in a similar situation to yourself. I primarly use Fruity Loops but feel the need to expand, primarily to get more quality sounds and to learn more about music production.
Some options for you and I include;
- getting a MIDI keyboard
(relatively inexpensive, approx ($150-$300). combined with some decent samples, soundfonts and VSTs you can make banging beats with FLoops and a MIDI keyboard)
- get a Yamaha Motif

(expensive but fantastic quality, approx ($2500-$4000)
- get a Korg Triton Studio
http://www.korg.com/gear/product_info.asp?A_PROD_NO=TRITONSTUDIO
(expensive but fantastic quality ($4000-$5000)
- other software options such as Reason, Pro Tools etc
(cost varies. powerful programs that when used well can produce great results.)
- other options depending on who you speak to or what you have available to you.
personally my next purchase will probably be a decent MIDI keyboard as well as learning Reason. Once I am making quality music with these as well as mastering Fruity Loops (now FL Studio) and am making signicicant $$$ from this, I will then consider a MOTIF or TRITON.
best of luck to you and let us know how you go with it.
p.s. I am not an expert in hardware or even software, the above is just my opinion from what I have researched.
peace
