My wife has been playing since before the invention of fruit. She's had a million gears, but currently has none. She's been giving piano lessons to youngsters, and business is exploding. She needs a keyboard quick. We have no keyboard amps, not that that matters, but we do have a Fender 15w bass amp and my Fender Princeton for now. HERE'S THE QUESTION, don't screw it up: She wants a full 88-key keyboard that she can just plug into one of our small amps and get some work done. If you would, please offer the cheapest recommendation up to a $500 value. We want to spend as little as possible. She doesn't need $6,000 Triton, nor a $199 Casio. Please suggest something real and useful and practical for her simple needs. Thank you, you wonderful people, you. The Vinsanitizer.
