I can only echo what has already been said about dealing with Mark. He's a top bloke.
I've had three Limelights in recent years. Two were OK - like typical parts (bitsa/partcaster) basses. One, however, was a whole lot better and had real mojo and played very nicely. So, somewhat varied edperience.
Never played a Nash, but they seem to be pricey by comparison.
IMO, the hands down best bass in this market sector is a Bravewood, if you can locate one. Fantastic instruments.
