Nash is a big favorite, but their prices aren't for the faint of heart.
There's a company called Vintage that makes some reasonably priced relics...I see several for $599 right now.
Jazzmanbass on Ebay will relic a bass for $299 and sells the ones he makes for under $1,000...good-looking stuff I've considered in the past.
For me, however, I'd go with EastGlove for $1,000 or so. I almost bought one last year but I went with a very nice Bacchus Woodline, instead...rare to see them for sale in the US.
Some people might say EastGlove relics are a bit extreme, but I think they're works of art.
