Never played an F50, so I can't comment.
I do have a line on a local B30 or B50 with hard case for $800 or less that, if you worked out a deal with the seller and paid for gas and shipping, I'd go fetch for you. All I'd want is a chance to do a write-up on a head-to-head comparison between the Earthwood and the Guild in my own home. Message me for details if you're interested.
