yeah i think the ultras are the ones where i have seen the difference on friends of mines cars. ill get new ones when i get new head lights in a month or 2. i didnt look at the links, but how much you planning to spend on the HID's? I mean if you just like the cool colors that come with them, then by all means get em. i love the look, but just couldnt see spending the money on em. then again, im a performance over looks kinda guy.
