wet or dry suit?

Hi.

I'm about to buy my first suit which is going to be used along UK South
Coast and various other locations in UK. I've been looking on the web
for reviews and advice but I get conflicting information. The majority
seem to say that it is best to buy a dry suit straight out which are a
couple of hundred more than the wetsuit I'm looking. I can try the suits
on but the shop may be biased so I'm after some independent advice.

Could anyone tell me if a 7mm Cressi Lontra 07 with the jacket/hood
would be warm enough for dives down to about 30 metres? Or is a dry suit
necessary given that I do feel the cold quite a bit which is what I want
to avoid as I think being cold would ruin the whole day for me.

I'm thinking about buying a cheap 3mm LOMO suit for pool use and either
the Lontra 07 or a dry suit for out in the sea but I am unsure which
route to go down. The extra couple of hundred £'s isn't a problem but I
can't afford both at the moment.

thanks for any advice.



Neil
