correct me if im wrong but i believe there like an SAFC and VAFC in one, so if u aint got Vtec its probably not really worth the extra cash over the safc unless ur a sucker for pretty displays
*EDIT*
i just glanced at prices on ebay between the SAFC II and the NEO and theres not a whole lot of difference..so u may as well go for the NEO and get a funkier looking unit!
