Dionne, the one HUGE pit fall I found with the re-usables was not the nappy itself but the wrap (cover). So many of them leak!
If you just want to try one kind I would highly recommend OneLife or Motherease, as these make the wraps I think are the most reliable.
Totsbots and other brands are lovely, but the above two 'do exactly what they say on the tin', without being too pretty.
If you're not bothered about second hand how about trying a nappy library first? Maybe Coventry have one? It's wear you borrow some just to see how you get on. You could try different ones then
