Your body is naturally bouyant - so you don't need to be half as worried about your weight as you might think.
Much more important in your risk assessment is - why are you in the water (are you conscious, unconscious on entry) and what you are wearing. Lots of foul weather gear, big seas, unconscious body - you may need more than 150N. Bikini, flat calm swimming pool, conscious on entry and become unconscious - 150N is plenty. There is a spectrum in the middle somewhere...
im thinking of the salt tablet type will that be ok getting splashed with water or will it go off.
Most people on here use the tablet system. A few use the hydrostatic system. Hydrostatic has the disadvantage it needs to go about 1m below before it pops - so you go under before it goes bang. Having popped a tablet one by mistake a couple of weeks ago you are far less likely to get under.
The tablet is inside the jacket - it takes a lot for spray to get to it. Yachties report them going off in lockers. So I think there is more of an issue of longterm storage in damp areas that weakens the tablet than spray. There are people here who will confirm they've had tablet ones pop in a huge wave.
My biggest challenge is launch and recovery - misjudge and its deeper than expected and pop. If you have the bouyancy aid - can you switch once away from shore in unknown teritories?
anyone got recommendations for good quality kit at reasonable price
Two things you need to do - determine a specification and determine a short list of manufacturers.
Do you want standard design or something designed for comfort (e.g. Kru Sport or SpinLock style)?
Newtons. 150, 175 or greater? (I think most here stay under 200N)
Spray Hood? Does your risk assessment identify that you might be in the water for some time awaiting rescue? (If it includes a PLB as a means of alerting & rescue it should!) If so do you need a spray hood?
Do you sail? If so integrated harness? If not pointless extra weight.
Crotch Strap should be mandated
Do you operate at night/dusk/close enough to night that a rescue might be at night? If so do you need a light?
33g slightly easier to obtain than 38g CO2 if refill needed short notice. But wouldn't suggest that should be the decider.
Personally I use a Kru Sprot Pro - can't fault it except iot didn't come with light, if I was buying new now - I wouldn't rule out looking at Decathlon's clone of the SpinDeck. You probably won't go far wrong with most known brands like Crewsaver etc.
