There are several people on here with the pods fitted and I have posted a thread up in this section somewhere.
Gauge fitment depends on what ones you go for. The Defi's are about the best with regards quality and easy fitment with fewer wires. Some cheaper ones out there have a lot more wires to hide up and connect.
Honest opinion is pay a bit more for the gauges (Defi) and they become neater and actually easier/cheaper to install.
