Hello good people

I've decided to take up model figure painting after a significant layoff (to say the least). I've ordered about £70 worth of 100 years wars rolling into WoTR medievals perhaps with some skirmishing games ahead if I can find a Tyneside club. I'm hoping you can save me alot of money messing about with various makes of paints and techiques before I get to where I want to be.
I used to undercoat with Humbrol enamel choclate brown back in the day, paint faces first, them metals, generally using humbrol enamels with some citadel acrylics thrown in there then sometimes i'd wash clothes/faces with an oil paint and drybrush figure with a white. Id quite often re clothes etc base with a dark colour then drybrushed over with a lighter tone of the same but never more than two colours/multi tones.
I'm wanting to go to acrylics full stop as i have my own home now and whilst smelling my parents keep out with thinners wasnt an issue my own little blot on the landscape is another issue!
Im thinking undercoat brown except for metals (black), but what paints would you recommend gents, water based only no more enamels or oils.
Id be really, really grateful for any help as my little lead heroes are on the way from Front Rank and some random castings from ebay to get me warmed up as we speak

, I'm thinking about just using citadel paint again as its readily available over the counter and im lost on mainstream art shop makes
