Whatja think?

Hey all, I want to go to Australia on a working holiday visa this year
and a friend recommended that I use this company:

http://www.overseas-emigration.co.uk/workingholiday.php

Except seemingly they'll give her a free Lonely planet guide if I sign
up, so her opinion may be biased!

What I'd like to know is has anyone used them? Or can anyone recommend
elsewhere - I have heard some bad stories about people not getting
their visa and travel plans messed up so I want to make sure I'm going
with the right crowd!

Cheers

Jay
