I would go to Sam Ash or a similar large music store to actually touch the keys and hear the sound before buying online just by a model recommended. You might not like the touch of any given keyboard, where as someone else might love it.

Play them ALL in your price range, even if just tinkering. KNow that are organ type feel keys to many on that price range, with some models having a more piano-like feel. To get close to the feel of a real piano, you would need to have it the specs say it has "weighted or slightly weighted keys". Weighted would be my choice. But they come at a higher price. Casio will probably give you more features for the same price as the Yamahas,,,but not always....lots of models out there and depends of sales and what you can negotiate with some stores.

Sales are down for retail stores, so talk the bargaining talk to get the best price...Maybe don't buy that day...Leave....come back in a few days, (NOT eager to buy),,,, to see if the manager will go even lower for you. They want sales! You may get a decent real piano-like feeling keyboard with good sounds for not that much more than your 250. Maybe even around it, if used.

Many models. Search more online just to get an idea of all of them. get ot know the model letters and numbers. Write them down and learn them. BE a keyboard guy!

Don't just get one online without first playing one somewhere.

Good hunting!
