Craig's List has a Casio AP-21 that's "virtually unused". Is this a good buy for $450 (assuming it's really in such good condition)? I've heard they went for ~$1200 back in 1999, but that means the keyboard is almost 10 years old.
Thanks!

$450 is way too much. For example, you
can get a brand new Casio PX-700 with full
warranty and better overall specs for
$500 at some discounters. The AP-21--
provided it's in perfect condition and
has weighted keys and an integral stand with
built-in pedals--is worth only about half
of the asking price, no matter what it
sold for new.

i would be cautious about a 10 years old digital. these days technology advances fast, and today's new models would be perhaps 5 times better than old ones. so the price for it doesn't mean that much.

if i were you, i'd check its specs first to see if it still acceptable by today's standard. if not, look for something else.

I currently have the Casio Ap-21. however the Main PCB board needs to be replaced. And that alone costs $500 from Casio Parts Direct. So if the one off Craig's list burns like mine did 1 day ago, you will be stuck with a dead unit.
