as has been said a/g biab is not all that hard all you need to do is hold your temps for 60 to90 minutes and the malt will convert to sugars, there is a heap of recipes on the recipe thread for you to brew something you think that you will like. and yes you will have to be carefull on the cold side (post boil) cleaning and sanitation are more than important they are vital to good brewing and yes a cheap fridge and a temp controller is as important as good yeast for quality beer. all in all my advise is go for it but be preparedf or the hobby to be all consuming.
