I already have plenty of "crazy lag". Still, on the rare occasions when the notion occurs to me of dropping an absurd amount of money on a frame, I always think I need yet more "crazy lag". (On a larger frame though. And one with brakes, and cushioning on the handlebar.)
For those with deep pockets who enjoy spending piles of cash and would get a buzz out of the "3rensho" name, then yes indeed, why not? But the bottom end of your price range would I think get you a made-to-order frame (for your dimensions, not those of somebody in the past) from Ravanello or similar, plus non-rare but good parts.
(If it were Ravanello, then you can see just how much it would cost, though only in Japanese. Alas "crazy lag" is not on offer.)
1. nobrake laws rarely enforced lately is the voice from the street, so risk to get fined is very low. Considering it's still a crime and you will be in deep trouble, plus non-insured if you hurt somebody, wouldn't recommend it.
2. For custom Japanese frames you can't beat Equilibrium Cycle Works for price and waiting time for full-custom. For 3rensho et al, non-Japanese communication will be more tedious and waiting time 1-2yrs!
I meant cherubim. Nothing wrong with a 3rensho, although I personally prefer zunow I it comes to dead stock. Wouldn't ride either, as there are probably none fitting me, nor would try be affordable if they did.
