The lack of information about each gauge package leaves a lot of questions unanswered.
Some gauge packages show a mechanical temp gauge and an electric oil pressure gauge with a sender, and a fuel gauge with a sender (for $54 with free shipping!), but some packages only show the 6 electric gauges ($45 with free shipping!). Electric gauges without matching senders may be worthless, or the senders may be included, anyone's guess. What about the speedo, is it cable driven, or does it require a sender, or is it GPS? Lighting package included, or even available? Also don't know where it might be shipping to you from (that might be reveled in the buying process).
India is currently the lowest labor rate country, it has replaced China as the cheapest place to have stuff made, and you may be buying directly from the manufacturing company.
I'll wait to see how someone else comes out.
