You have already got a set of lights on the top of your light bar, right?
The Techy bit:
These lights will either be fogs or spots (we'll assume you're an educated man and know the difference

) This means the ones you fit to the bottom will need (well should be anyway) the ones you don't have on the top ie fogs on top and spots on bottom (though technically the fogs should be the lowest). Generally the fogs are used on the GSs as daytime running lights, because they throw out a flat wide beem that can be seem from more angles than sopts.
Micro DEs are available in fog or spot configurations. However the thick domed lens gives a milky kind of light, with no dicernable clarity to the light given out. So in my oppinion these are better used in their fog light guise.
The FF50s mensioned above are also available in fog or spot configurations and work well in both guises as they have normal glass lenses. Thay are a completely different shape to the Micro DEs though. So might not be what you are after.
Now, To answer your question, Is there anything like the DEs out there that are recomended?
Yes there are hundreds for you to choose from. Some good, some not so good.
Ebay is your friend here.
However, The reason you are getting so many recomendations for the Hella FF50 is that they are very good quality and can easily be upgraded to HiD. As can the Micro DEs. Less Wassell is your man for that.
I will add here, The Micro DEs are really quite heavy, so make sure you light bar is up to the extra weight.
Check what you have already and fit the opposit. What you fit only you can decide. Good luck
Val.
