here is a good overview of JJP

here is the initial set price:

- deposits taken before 1st March 2011 for the standard were set at $6500 USD
- deposits after 1st March 2011 were $7500 USD
- and pretty sure the le's to follow were $8500 USD

this coincides with the AC/DC pricing jumping up on release as the start of WOZ production


then Nov 2013 a new LE is announced at $9000
