big big difference.. but its nice.. at first i thought it was too weak.. but hooked to the pc (midi) with a sequencer its decent.. instruments are nothing to wow over.. tho i do like the onboard effects.. however i mainly use this keyboard as a midi controller.. just to input ideas onto the computer.. definately a good first keyboard.. even at the low price i would like a way to repatch this thing.. which it doesnt have.. and the onboard sounds again are not that great.. piano sample is the best thing..

The grand piano sounds great on it! The velocity could be a little better, you have to really pound it to get sound out. Horns aren't bad, drums are crap (on internal speakers).

I have not hooked it up to a system yet. One downside is headphones is the only audio out.

I also wish it had more storage, 3 or 4 songs is about all it holds.

All in all for a first time hobbyist keyboard, you can't do better in this range. As you go down in price, the sound quality drops considerably. This is a good one to stick with.
