slate calls,I have plenty of glass/crystal calls.

I am looking at the Steve Harrison osage orange slate,talkin' stick,cane creek,woodhaven,lee's champion slate,ray tom,s&s,tom teaser,and light's out honey locus.

If I had $400 I'd buy them all [8D],but I can only afford 2 of them,and I am having a hard time deciding,especially when I can't hear them for myself.I didn't know who the more popular makers were.Thanks for any help!
