People I am a long time guitar player and into music for quite long but even dont know the difference between a Keyboard and Synthesizer. Would be glad to have some info on that. I am planning to buy the Quickshot MIDI keyboard for my PC, its about $120. Is it worth that price or can I buy a used Keyboard or a Synth for about 200-250 bux which would do better than that for a beginner?

Please advice on these and also if you know any sites where I can find useful info on keyboards and synths please tell, I ll appreicate.

Thanks guys!
