I'm keen on modern updates/aids so electric start is a plus for me and as for an oil pressure gauge, well I've bought an A10 which had seized up when its oil failed to return to the tank with its previous owner, so an oil pressure gauge mounted between the clocks will help put my mind at rest as I blat along. As far as it being a breakdown waiting to happen, ok agreed, but it has to be done properly in a correctly engineered way and someone I know with the gauge has not yet had any problem with it, in fact, on two occasions he forgot to open the oil valve (manual anti-sumping) on the oil line down to the engine and spotted it on the gauge before he had moved a few yards.
Regarding a belt drive primary (like on my Goldie) which I want to use to run a dry case, unfortunately with electric start the primary will still have to run with oil to lubricate the electric start gears, but a belt is preferred to a chain anyway, so electric start it is for me.
Hope to hear good news from Steve soon.
