As far as Ellipsoids go, i have to agree with Doogle. While I haven't owned Depo's, when I began shopping for headlight upgrades, I spoke with numerous folks who had. EVERYONE of them wound up replacing them with Hella's or ZKW's. I bought ZKW's just because they are the oem replacement across the pond. If they are good enough for BMW, then they are good enough for me. Plus they look mean as hell, i think the Hella's look aftermarket (and IMO, kinda odd)!
