gauges
 

i've got a boost guage on the car, but have been advised it might be a good idea to keep an eye on the oil ressure and temp, and possible some others, my question is, shall i buy all these guages, and something to put them in (which i'm sure i'll like the look of) or is there one device that I can simply plug into the obd port and have all these things on hand? or even one device with many different connections for the senders etc? and if so would there be much diffrence in buying say one electronic device, or many anolouge ones(which surely would be more expensive, electronics are soo cheap at the mo!)

For an 'all-in-one' you'll be wanting one of these.
Still require the fitting of senders if you want oil pressure and temp though.
