I like all kinds of necks, though really ultra thin aren't my thing.What kind of necks do you like? Are you comfortable with your EC-1000 or do you want a different feel? I've played quite a few different guitars over the last couple weeks so I may be able to help a bit.
I love the neck on my EC1000, the only thing I don't like is the poly finish.
I've got a Schecter C6 Pro and that's got a great feeling neck too.
I suppose the obvious thing would be to get a satin EC1000. But I like aesthetics as much as feel and want something a bit more wood on show, hence my interest in the Schecter models I mentioned.
I do like the look of the KM6 Artist but that's heading into money I can't really afford.
