Fog light options - OE or aftermarket?

My '07 SR5 did not have factory fog lights installed and I'd really like to fill those holes in my bumper with some nice lamps. What do you guys think? Should I go OE Toyota or is there an aftermarket option that makes more sense? Only hitch is...they have to mount in the OE position.

 

Some people have mounted PIAA 510s in the stock location. I think it looked pretty awesome! I'm pretty sure it was Blackhawk and there was at least one other. I'm looking into it for my truck but gotta save my money up. If you want OEM, post up in the Buy/sell/trade section, someone who put on an aftermarket off-road bumper may be able to sell you theirs.

Dark Knight had the 510's as fog lights, not Blackhawk.
