Best Semi Permanent/Permanent Camping Tent

I am looking to purchase a tent that will be erected for approximately 6 months of the year on land located in a low-mid rain fall area in South Australia. I am familiar with the Campor tents but was interested if any other, cheaper canvas tents that are currently on the market would be adequate. Size doesn't really matter as it will be used by no more than 2 people.

Any suggestions would be much appreciated.
