Classic VW Beetles and Campervans

So, I want something which is a little bit of a project – something which I can use as a toy at the weekends.
I am currently liking the idea of a VW Camper Van – a Classic one….

Thing is – some come expensive some come cheap – I know the expensive ones are re-con’s and also you can buy a brand new one from Brazil – built by VW Brazil.
Anyone got any experience of these? What to look for – the usual thing like making sure the chassis is sound …
