Having just gone through the exact same process, & looked at what was available I've found that:-
a, the Fladen gear is very good value for money
b, the sundridge & other suits aimed at beach fishermen are cheap & cheerful but watch the quality.
c, drysuits do a good job, but can be expensive, sweaty & not as easy to get on & off, especially for a laydee.
d, Mullion is top quality & aimed more at the commercial end of the market, they do an "aqua float" range that is similar in price (sub £100) to the Fladens, but I found them a bit stiff & "cardboardy" The aforementioned 1MG9 suit, I found to be excellent for comfort, quality & functionality, but it's at the upper end of the price range. £200 quid'ish, but still represents good value compared to a drysuit.
