OilTemprature/Pressure Gauge Dials ?.

[Duffers60]

Would be grateful for any input on either or both Oil pressure/Temp gauges for my Bonneville T100 2014 , what to buy where to buy and peoples opinions on them.
Seen a couple of Google pictures and they look good but are they worth it.

Thanks in advance
