Scottyee and others here own the prs2000 and they can tell you the answer to the prs2000 question. If it's like prs9000 or 9000 pro you can adjust settings in control panel.
Maybe ask the saleman if he can plug the psr2000 into external speakers. By "weak" did you mean 'soft" or "not like a paino sound"?
I know when I close my eys and just listen to my psr9000 it sounds just like a paino to me ... as others have said ... we all have our opinion on the subject.
In addition to just the "paino sound" when you are buying an arranger there is so much else you are buying! Harminiser,Sampler,karakie with words displayed, midi, and these are things that you can't really check out at a music store... once I took the psr9000 home , and read the manual and chatted with others on psr styles forum ... and downloaded styles,pads,registrations, and was told how to adjust the control panel to make the sounds really SHINE ... I was very impressed!
That's why it is important to keep an open mind and ear and listen for yourself.

p.s. If you gig alot , the psr2000 is good choice and is the cheapest of all the keyboards that we have listed for you ...
For me,I don't gig out much and I liked the Strong Sounding Speakers in the psr9000 and Sampler,and 128 poly , styles,ect.
I think it comes down to just yourself, your friends or audience can't tell the difference, you are the 'only' one who is gonna be that discerning!
