Not me. Overpriced. You can get a set of Testo 550's for about a hundred less. The Hilmor gauges look large and bulky. Apparently the dials are driven by stepper motors (?) - lots of room for error there. The pipe thermocouples look like cheap plastic that will break after a few uses.
The actual manifold is the only part that looks decent.
Maybe Mark can answer this question, is the gauge housing made of plastic? It looks like plastic.
These are just my first impressions. I still would like to get my hands on a set and test them out.
