... and organise a representative to attend the settlement, perform title searches, various registration searches, due diligence, etc.
$450 is a bargain basement price and for that, they're going to cut a few corners.
For a regular residential transfer, personally I go with a conveyancer over a solicitor. They tend to be a little more cost effective and they're usually better at it because it's all they do, all day, every day.
You do need them to have access to a solicitor if things go pear shaped however. The person I usually recommend has a team of property law specialist solicitors right down the corridor in the (extremely rare) event that they're needed.
Most of the problems I've seen with conveyancing occur when it's a solicitor doing the work. I'm sure they're good solicitors, but conveyancing is not what they do most of the time.
