Gauge question

I plan on buying gauges to prepare for a turbo in the near future, and of course have come acrossed a wide range of prices. I was just wondering what the difference between a gauge like that Auto Meter Cobalt series (http://store.summitracing.com/default.asp?Ntt=gauges&x=0&y=0&Ntk=KeywordSearch&DDS=1&searchinresults=false&N=0&target=egnsearch.asp) and something like like the REV2's (http://www.autodynamic.com/search_results.asp?iLevel=1&txtsearchParamCat=ALL&txtsearchParamMan=ALL&txtsearchParamVen=ALL&txtsearchParamType=ALL&txtFromSearch=fromSearch&txtsearchParamTxt=REVO+REV2). Sorry for the long links. Is there that big of a difference in gauges, and will the cheaper ones give me less accurate readings?

the only 2 gauges i see that are good is the boost and oil pressure gauge

Do you mean that those are the only two worth having? Because I was asking about the difference in brand. Or are you saying that those are the only two good ones in one of the brands?

oh which is better, well defi gauges which you dont have listed is the best but i would say the rev2s are better

alright, what gauges would you recommend? I kind of like the blue LED aspect too, or even a greenish color to go with the Prelude interior lights, plus my headunit lights up the exact same color. Thanks for your help though.

what ever brand it is.

AF w/wideband, egt, boost, and oil.

i prefer the first three.

ok, so is the bottom line here that brand isn't all that big of an issue, as long as it's not like a complete cheap piece of crap?

well idk about any brand like i said defi is the best but the most expensive.

and what super listed are the best gauges to get, and to clear it up, hes probably talking about a oil pressure gauge, those are the 4 gauges i would get
