I think Dakota had the market cornered for awhile so it could charge more to be honest but their quality is very good and the gauges are worth it IMO, along with some options to add on that are plug and play. To get the PRND indicator you need to spend about $100 for an add on module, not needed but I wanted that back in the stock location, plus you can add other modules for different readings that will then display in the gauges. I bought the A/F ratio one, a valuable gauge I think. I also spent another few hundred to get the gauges customized (working with Dakota Digital) to mimic the 86-88 Monte/El Camino style. Absolutely worth the splurge to me and these are available from them, Mike's Monte's carries them too. I copied the idea from another mcss.com member who had his customized to match the 81-85 styling. I added the yellow 5500-6000 spot in the tach as a nod to the non SS tach which has a little different coloring/lower line than the SS.
I guess I can't speak to the quality or look (first hand) of the Intellitronix gauges. Digital readouts are kind of cool, just not my cup of tea, at least not in my car/build. I also did the VHX starting in 2014, got the current style in 2015, not sure when the Intellitronix came out as a setup to compete with Dakota Digital, feel it was after this time period.

Side by side of the original one I bought and after receiving the custom one, took awhile and back and forth with them to get it dialed in.

The A/F ratio gauge, had to add the bung/sensor and controller from another company that worked with the VHX module to display in the cluster. I think you can have 2-3 add on things to the cluster that they offer.
