Sway bars....

Looking to install sway bars on my 02 4WD Hoe... I've narrowed the decision down to Eibach and Hotchkis... Eibach's best price is on Autoanything.com @ $287.95 (free shipping) and Hotchkis @ $502.16 + shipping @ Hotchkis.com.

Anyone installed sway bars out there that could lend any advice?

Thanks in advance!!
