I don't know what to say - I have never played stick nor warr. For me sticks and warrs are expensive - cheap guitar You can buy for 100 USD, cheap stick for 1100, but remember - You would need two amps, special strings, case or something, so You'll probably need about 1600 USD. I saw cheaper form of tap-instruments at Mobius Megatar, but still they are expensive to me.
MIDI pickup and module is very expansive.
