As far as I'm concerned, I always loved Durst. They made some of the best enlargers out there. The only thing about them is that there are fewer parts floating around on the used market so you have to make sure you get the whole kit or else it might be a while until you find what you're looking for.
As for the price, it pretty much depends on the local market. Here in Quebec, the market is pretty much dead for lab gear so it's easy to pick-up good gear for peanuts. But it might not be so in Australia...
Just as a comparison, I got an Omega in mint condition for free when I bought a 175$ Graflex...
But let me tell you that I would definitely have splurged on a Durst.
