Custom fuel tank?

[postalWagon]

Does anyone have any experience in getting custom fuel tanks made? I want to replace my small, probably rusted, stock fuel tank with a full width under seat tank.
any pros or cons?
how much should I look to spend?
where should I start looking for a shop?



(I posted in both general modification sections.)

there was a thread a while back on Aero fuel tanks. I have one on my CJ and like it.
