Food for thought here. I'd also look carefully at Otter as I have plenty of friends who use them. My wife started using one last year too and is very pleased with it indeed - she has even used it for her work diving despite having a (Gates) work suit provided! Otter aren't the cheapest but my experience with the more expensive DUI is mixed. Its very comfy but simply not as watertight as it should be (and never has been) unfortunately. O3 do have a good reputation but are in the DUI price bracket too.
The best suit I have ever had was an ex-NATO Avon - £80, lasted many years, very, very dry, quick drying, comfortable - a superb suit. But when I asked the company who made them (an ex-division of Avon) if they were likely to make any more I was told (several years ago) that to sell them at £1000 would not be profitable. I still have one but is is porous now and the seams are shot - it is 20 years old though.
