Just get greaseable ones. If ford made parts with grease fittings on them I think I would not be so pissed at them. I dont get this new trend of no grease fittings and having to replace parts...
I just picked up ones from NAPA for 15.06 after tax for each one. Good luck trying to change them. I couldn't even get my driveshaft off... it must take superman or a impact wrench... somethings not right the shops doing them now.
You can go for any other performance brand as well... just get ones with a grease fitting... they can last much much longer.
