Well as the saying goes 'you pays your money and makes your choice' getting rid of points heel wear and replacing with an electronic trigger makes some sense but there again the points are doing far less work and a little bit of grease on the heel once a year is hardly onerous. For appearance i would go for the in dizzie type, however, for ease of switch over in case of an, albeit unlikely, fault in the electronic box the external units win hands down. All have their followers but the unanimous opinion is that it is worth fitting an electronic unit of some type. Let us know what you opt for and why.
