I ordered from here:

I installed myself, once I got the correct tools and understood what I was doing it took 10 min per light maybe a bit more but very easy. That coming from someone who has not done much work to my car. Also the price isnt too bad.
I havnt taken it in for service but I dont think it would be an issue.
