CASIO VL TONE 10

Ok, so I'm going to buy one of these from an auction site.. How much you reckon the MAX price i should pay? At the time being it's going for the equivilance of 20 Euro... But that's prob. going to be abit higher..

And yes it's a CASIO VL TONE 10, not 1... I really don't know much about it, I just want something to bend that isn't just toys.. Yeah yeah, it might still be a toy, but it's not some shit from you regular Toys'R'Us... Oh, is there any bending info on this bastard? I haven't been able to find any. I can only find stuff on the VL TONE 1...

Oh yeah, this is my first post here so, well, I here by welcome myself :-D

EDIT: Ooopps, well it was my second post hehe... Anyways..

2'nd EDIT: Ok it went for around 55 Euro.. Decided it wasn't worth that much...
