The above top pic is my '66 J. I built it up (actual '66 J body, custom neck) 11yrs ago, before Gotoh offered their pops. A guy on eBay used to modify standard clover-paddle tuners by grinding off the top 'bump' and polishing the edge - turning them into pops. He did good work and you have to look very close to tell how they are different. I had two sets made that way.
I honestly think that's too much for any set of tuners, even new. Also people are trying to sell individual Ibby tuners for like $50-75 each. Ridiculous.You won't get that much- somewhere around $100 or possibly a bit more.
Personally, I'm holding out the for the set - one liver, one kidney, one spleen and one colon.
I like looking at exotic-wood basses as much as the next guy, but I'm not drawn to them personally (for basses I play). Seeing this example with the cascading figuring inspired me to do something artistic with gilding. Something blue, because it reminds me of water. We'll see.
I'm willing to pay $100 for a set of lightweight, nicely engineered tuners: Gotoh GB350s or Hipshot Ultralights.
One can buy cheaply made generic MIC tuners all day for very little, but I agree - anything under $100 for a nice set of quality tuners would be considered a bargain. Gotoh and Hipshot make quality tuners.
It really is a personal thing. The wide range of ultra-cool finishes you have done make it very clear that your artistry provides different and wonderful options that can be way more interesting than simple wood. Your finishes have a pizazz that is missing from many exotic-wood instruments.
tanks man! The only other time I did a sorta exotic (spalted maple) wood / gilded mix was one of my first Gildaxe custom basses from over 10yrs ago. Pat Wilkins did the final finish - my first dealing with Pat. I call this finish "shatter-burst". The person who bought it years ago said; "it's following him to the grave". Can't get a higher rating than that! 
I asked for a fb ramp but I can't tell if they did that. If not I can do it myself - no biggy.
The 32" scale neck has 24 frets. I primarily wanted the extension/ramp to cover the vintage pg's truss-rod cut-out as the China neck has a hs tr access.
