Get LED's, they're more reliable and won't set your car on fire. As far as who to buy from and why, my recommendation is to get a set of used V2's off a member here or one of the other forums. The reason is that you can get a set of very reliable V2's for ~$100 +/- shipped. Whereas, if you buy from ddm, their budget angel eyes after shipping, duties and brokerage fees will come to the same price range (ddm ships with ups). So you either get a new kia, or a used bmw...I'll let you decide.
After you get them installed, you will need someone to turn your drl's off (reprogram the lcm). Don't go to the dealer for this, there's a good few people here that have the software and hardware to do it for you for some nominal fee.
