How much are NEW 03/04 Manley Rods worth?

[svt32v99]

I have an opportunity to pick up a set. I won't be building my motor for SEVERAL years but I could trade my old IRS (upgrading another IRS for my car) for a set of brand new Manley 03/04 Rods. Is it worth it?

Edit for horrible English...I need to sleep.
