I am in Sydney and I looked at the Bell Canvas trailers and thought they were OK but we ended up buying one from 3dogcampers in byron bay, because a friend bought one and when we looked at it the finish was excellent. I also looked at some at Kangaroo Tent City (parramatta) they will actually fit a camper to your trailer, and just this weekend gone I saw someone selling ones at the Blacktown Drive-In markets, from $6,000, they actually looked pretty good too.
I found the ones from Tent city to be a little rough, small things like giving you 2nd hand tyres etc. Also we ended up with an aluminium trailer as we needed it to be lightweight as we only have a 1.8L car.
It gets hard and the price definitely adds up but for me the quality of the finish was really important as I intend to keep it for 10yrs and then hopefully sell it or if we find a place we love perhaps sell it for an on-site van.
