A Minefield

I am brand new to Motoring/Caravaning and am looking to buy a motorhome at the end of this year/ September time. Where I live it is not easy to go looking around at motorhomes so most of my reserch is done on line and through the club site. The problem I have is that I just dont know which one to go for, there are that many out there that they all look the same after a while. I have a certain budget and am thinking that when the time comes to buy one in that price range. I am sure that lots of other people have been in my position so if anyone has helpfull advice I would be greatfull for it.
