I sometimes offer my set of Gen-1 Special Edition '13 BLs up for sale for ~$1800 and all I get are bottom-feeders who complain that the new but old tires are a concern. I'm just waiting to until I wear out my current set of tires and will run them. They've been out of the UV light and temperature controlled. The rubber is as pliable as new. Even if there comes problems with being old; so what, replace them. Wheels & tires only had 25 miles on them. I later bought the new bead-lock rings & bolt kit from Ford too. Anyway, if I get the right price for them I may sell them; if not, I'll run them soon enough.
If I have to run aftermarket, I'd go with Method wheels then get some billet hub adapters made to help make it hub centric; otherwise, OEM wheels are always best since most of the time the aftermarket will-not/do-not make wheels with the same specs as OEM (e.g. offset, hub diameter/centricity, & etc.). On some of my rigs, I have my OEM wheels converted to Bead-locks, and that has been the ticket for goodness. No wheel bearing failures or odd steering feel--Just Awesome!!
In terms of price, it's all over the place, and you'll have to hunt down wheels on a daily basis on CL, eBay, and swap-meets/expos/etc. You'll just have to decide how bad you want them if you happen to find one that might be 6hr+ drive to get them or ship them to you.
