G'day Erik,
I have the Astro-Physics 27TVPH which works well and provides a fairly large image circle but you'll probably need some adapters to put it all together. The A-P CCDT67 is also a popular choice. It's more convenient and has a higher reduction factor but a smaller image circle.
Some tech details here:
