I tried them today, and am pretty much decided on the Valentine BFR walnut.
It felt perfect, sounded amazing and looked even better. I also really liked the Mariposa BFR. The neck(mariposa) was very narrow, but nothing I wouldn't get used to. I'm just thinking it may ruin me for playing my other guitars. I still have yet to try the Sabre HalfBaked, which I will this week, then decide.
I can definitely confirm that these are the absolute highest quality guitars I've played, and right now I'd rather have a high end production model than a custom build, since I wouldn't be able to properly spec a tailor-made guitar. I'm more of a try and buy what I like type.
