I'm GASing for some gear... but have no idea what order to get it in...

I need some help... so i've come to the Pit with all it's infinite wisdom!

MXR 6-band EQ (for my VK)
Tech21 SansAmp GT2 Tube Amp Emulator pedal (for my VK)
Shure SM57 mic (for recording obviously, i want to put up some mp3s)
□ Keyboard (don't know what kind, but it'll be around $200)

i'm really leaning towards the keyboard... or the mic...
