I am looking to get a drop in replacement boiler for my system, It is a Primatic fed central heating system, and what would be the best boiler to replace the exsisting Ideal Mexico Slimline

can't
you will need to replace the primatic cylinder too, because your gravity hot water will have to be replaced with a fully pumped system to meet the energy efficiency regulations and you can't have primatic on fully pumped system as it will dislodge the air bubble.
or you can rip the whole lot out and put a combi in.
