im looking to buy a 4:22 gear set. Must be in good condition of course.

I know this is probably too good to be true... but... I just have to ask!   Is this worth buying??     http://www.ebay.com/itm/1991-1999-Mitsubishi-TD05-20G-Turbo-Eclepse-DSM-EVO-GSR-VR4-/200822897500?pt=Motors_Car_Truck_Parts_Accessories&hash=item2ec1fa3b5c&vxp=mtr           http://i.ebayimg.com/t/1991-1999-Mitsubishi-TD05-20G-Turbo-Eclepse-DSM-EVO-GSR-VR4-/00/s/MTYwMFgxMzUx/$(KGrHqZ,!o4F!I(z(SMqBQEdUPHy7Q~~60_57.JPG

Not sure if we are allowed to post links to places but im just wondering if anyone has used this head on their engine. Seems pretty cheap for a new head?   http://www.oreillyauto.com/site/c/detail/PTQ0/2281/02257.oap?year=1987&make=Mitsubishi&model=Starion&vi=1208203&ck=Search_02257_1208203_2985&categoryRedirect=02257&pt=02257&ppt=C0332
