Three keyboards?!?!?!? I'm five years into production and I only have two. And one of them is an Oxygen 8.
The other is a V-Synth. Can't scoff at that one. I make hip-hop, and am a music theory man, so I don't have a use for 88 fully-weighted keys as I am a one hander at best (Mostly stepwrite/build up melodies/tap pads). And if you ain't no Mozart on the keys yourself, don't get three. Sheesh. And don't get redundant geaar starting off. Here is a good and decent set-up to make beats, record vocals, mix and master on a budget that isn't going to make you look wasteful, but still give you a respectable set-up (as far as this site is concerned).
Computer 2gh processor/512 MB ram/80 gig HD/CD burner. $1000-$2000 depending on options.
Sonar 3 Producers Edition (Since you like Fruity anyway) $450.00
M Audio Firewire 410, you'll have to build up tracks two to four at a time, but if you are new to hardware, assignable outs will be lost on you anyway. $300.00
M Audio Solaris Mic. $275.00
M Audio BX8 Monitors $480.00
Roland MMP-2 Mic Modeling Pre $250.00
Motif 6/Triton Classic/Fantom S $1500.00
MPC (Since you HAVE to have a MPC; the MV is better though) $800.00-$3200.00 depending on the model. I say get the 1000 $900.00
Korg MS2000BR (if you are new to hardware synthesis, start here) $500.00
Turntable $100-$400 depending on which one you get.
Table top CD player. $200-$500 range
Mixer $200-$500 range will suffice.
Sonic Maximizer $200.00
Misc software synths/effects plug-ins/sample CD's $600.00 (Don't go overboard)
That will keep you busy for years. $8,000.00 tops. And if you drop all that at once, you'd be crazy. But if you got that kind of cash all at once, go for it.
