New to Synth

[OSS_Synth]

Hello, I had been playing guitar for three years when my friend asked me if I would play synth in his band. I've been playing the synth/keyboard three months but have picked it up a million times quicker then guitar, played one gig in front of about 200 people and went down well. I'm also having alot of fun playing round with the oscillators on my synth. At the minute I play a Korg x 5 and a Micro Korg.

I recently recorded with an Access Virus B for our band and was blown away by the amount and quality of sounds so I thought I would have to get me one of those. Anyway on doing some internet research I see that the TI Snow is most suited for live performance although I can pick up a virus b second hand for half the price.

What are the pro's and cons of each? I'm also prepared for a steep learning curve.
