Pro,
It's not the equipment--it's the performer. I've seen lots of performers that could keep a party hopping with an "El-Cheapo" keyboard that that sounds marginal at best--even when amplified. In contrast, there are a lot of indivuals who try to pass themselves off as entertainers who have incredibly expensive equipment, read and play music well, but couldn't fill a dance floor or please a crowd at a cocktail party if their lives depended on it. I've owned a dozen keyboards, some of which were really expensive, and to this day, no one has come up to me and said anything about the keyboard's appearance. NO ONE, EVER, AT ANY TIME, ever looked at any of my keyboards and said "gee you only have 61 keys. They don't care if it has 2,000 keys, or if the color is silver, black, blue, gold or rocket red--just as long as they're entertained. You would be amazed how many people do say, however, "We loved the music, it was very entertaining, and I'm glad that you didn't do what the last guy did and crank up the volume to the point where you had to scream at the person standing next to you." IMHO, in this business if you're not keeping people entertained, you're out of business.
Cheers,
Gary
