Hi Kev
I used to have a GSO deluxe that I had to collimate and disliked having to live with the sausage-shaped spot. I now have the HoTech laser collimator and like it. I'll report shortly on testing its internal collimation properly and showing that, as supplied from the US, mine is within the manufacturer's spec.

Bought it from a US ebay retailer before the Oz Dollar fell! Look for some videos on Youtube showing it in use.
I believe that Matthew Lovell (Telescopes and Astronomy
http://www.telescopes-astronomy.com.au/ ) is the Oz dealer.
I've seen good reviews of the Astro Systems barlowed collimator:-
