Dick, it will depend on what sort of budget you have. Tents have come a long way in recent years with synthetic dome dents being very popular and inexpensive.
Like Elaine said, canvas is great in many ways...except maybe cost, weight & care when wet.
When looking at synthetic tents, make sure they have heaps of ventilation & the biggest recommendation is to 'tarp over' irrespective as to whether you have canvas or synthetic. This will aid in keeping you warmer in the winter camps and cooler in the summer camps. It will also assist in keeping bird droppings and the like off your tent.
It will also give you an extended area in which to set up the kitchen and eating area.
Have a look back through the old posts and you will get heaps of great info & see some good pics of camps set up as well.
The worst day camping still beats the best day working
