Ok but why then do we get so many reviews of Romanians if the general consensus is that your guaranteed a poor service? Probably because they are cheaper. So laws of supply and demand means more reviews of Romanians, and therefore more bad reviews. But as a percentage are they actually worse? Dunno, just a thought. 
I wouldn't presume to say it is a general consensus of members, but it is a large number, yes. And, as I stated above, in my own personal experience, Romanian WGs do relatively provide a poorer service than WGs of other nationalities.
Some punters on here will have you believe that the more you pay, the better the punt is, which is total rubbish. I have a limited punting budget and have seen a number of reasonable WGs for £70 half hour.
You may well be right about the lack of choice in your own area, though there are some options for 70hh/100ph within an hour's drive of Winchester ie Southampton, Portsmouth, Bournemouth, Reading, Farnborough.
