I just use decathlon's wind proof jacket. It keeps you warm when the wind is blowing hard. I've not used top end 300quid jackets that are supposed to breath but I'm very sceptical that they don't make you wet underneath. You are going to be wet with perspiration anyway so go without unless you juat nèed and extra warmth layer.
I really don't see the point of running in a waterproof jacket. You are going to get wet anyway from sweating and probably more so if you are wearing a jacket.
OMM Kamleika is great. I have also used the Inov8 Stormshell which is a bit less breathable but vents easily. Both have taped seams and are suitable as mandatory kit for longer distane races
Montane Minimus has worked well for me - including on SDW50 in 2013, with awful weather after the first 3 hours (kit requirements are there for a reason, as those who had skimped and ended up DNF due to hypothermia discovered).
Dear, have you found? if not than I recommend you to buy Stormshell jacket, I bought it recently for my brother. If you want to buy another than simply search on google through it you will get many options.
Goretex Shakedry jacket. Buy it in the sales. Wafer thin but if it can cope with me cycling in the rain for 4 hours and not let any rain in - it's decent.

Some runners go for the high end, such as

but if I do wear a waterproof top its more likely to be something like

which is lightweight but not breathable, so on a fast warm run you end up sweating so much you might as well not have bothered
