value of Solton MS50 in good condition?

I've searched Google but haven't turned up much other than a post from last year in the buy & sell forums here.

Can anyone chime in on the approximate value of a Solton MS50 in good condition, ie. all buttons working, etc.

Set a price...don't know the value, but it's the same as my MS-60's without speakers. It's a lot lighter.

Let me know...
