I'd recommend a classic inspiration in your case then, but if you can get one with the upgraded co ax loom as it seems to be less prone to corrosion than the previous ones fitted. Expect to pay no more than £2500. You only need the flow stop if it has an adv fitted, it is preferable to dive the unit without the adv so you get used to running it manually and only use the adv as a luxury on the more demanding dives.
