Sunpro guages?

[lukecp]

Last year i modified the dash of my truck to accept a aftermarket tach, oil pressure guage, coolant temp. guage, and amp guage. I used a Sunpro tach, which i like so far, but i used some el-cheapo Euqus guages, and 1 of them stopped working, and the 1 other dosen't work all that great. So, i plan to get another dash from the salvage yard tomorrow, and modify it to accept new guages.

I was looking at Autozone, and they have a kit of Sunpro guages, with a volt, oil, and water guage for $32. My Sunpro tach has held up fine for more than a year, but are their other guages as good? I want something that will last for at least 5-10 years, not the 12 months of the cheap ones i have now. Also, which is better to have, and amp guage or a volt guage?
