Just for your information, a couple of 'blips'on the throttle prior to cranking the engine over has absolutely no effect at all---the standard carburettor on the 500/126 engines does not have an accelerator pump. The "choke", again on the standard carbs, is just a simple enrichment device---there is no 2nd butterfly to 'choke' the engine of air.
To answer you question---the whole point of "electronic" ignition, as against 'points' ignition, is that with any of the 'electronic' options, the points and the condenser, both possible sources of problems, are done away with. The simple and relatively inexpensive systems (Powerspark, Accuspark etc) are 'Hall' effect systems; very simple and generally speaking, reliable. They do have a POSSIBLE down-side in that they are sometimes affected by the heat of the 'cooling' air coming from the engine, which due to the position of the distributor, is blown over it. The "123" system is a much more sofisticated system and therefore quite a lot more expensive. The "123" system comes in 2 forms---either an 'add-on' which relaces the distributor cap and the bulk of the bits inside the distributor or, as a complete 'looks like standard' distributor. Not withstanding the above, maintained properly, and with a high-quality condenser (Swiftune SW.IG-CC) "points" ignition will give you very little trouble, and seems not to be heat affected. In the end, it is all down to personal preference!
