I have digital Smiths and am very happy with them. Only had two "issues":
1. A bit of faf calibrating the speedo - "Speedbox" on my phone, taped to the tank, made it easier.
2. Intermittent inaccuracy on the tacho. Solved using shielded speaker wire from coil - earthed the shield.
Given the choice, I would fit them again.
Cheers
