i was in this postion 8 years ago - and the devon course was recommended as 'the best' so that is what i took.

the devon school and the lch are the 'parent colleges' in the uk. other schools were started by their students.

the history of the devon school and the london college [the two oldest in the uk that are for non-medics] is that they were both started by the students of two druids [damonte and maugham]who taught homoeopathy from an estoteric perspective in london in the 60's.
so what resulted in the uk is an esoteric practice of homoeopathy, far from the hahnemannian concept.

'locally' teaching the scientific method there is hans weitbrecht in donegal and sheilagh creasey at the lch and westminster. also george dimitriadis in sydney australia, gypser in germany and david little in india.

david little runs a good correspondence course which i would think a good way to start if you don't live in donegal, sydney etc.
if you are interested, chris gillen might be able to advise.
