Hi Shane,
Not a cabin tent, but we have this:
Oztrail Tourer 9+. We've had it for a number of years now, and it's fantastic. Still gets regular use. Canvas is still in great condition, waterproof, stitching all good, etc. I wouldn't hesitate to buy an Oztrail canvas tent.
Having looked at the Outdoor Connection tents, I like them too. They do a touring tent like ours, but it's got a number of subtle, but very nice, modifications. If I was buying again, I'd probably buy the Outdoor Connections one. So if you're comparing those two brands, see if you can have a crawl over one of each actually set up - you might fond that one has some features/changes/designs that you really appreciate.
Long story short, I don't think you could go wrong with either. My experience is just with the Oztrail though, and I'd recommend it based solely on the great run we've had with ours.
Cheers!
Matto
(Who still has an Oztrail nylon dome tent in the bottom of the laundry cupboard. I think I got it when I was 16. It's still in prefect shape
