Thanks guys, happy spending 3-5k - Ideally on something which could serve more than one purpose - will look at the circular saw with track guides.
I find myself often having the need to cut straght or square cuts doing home projects, and my hand saw with mitrebox, or jigsaw just don't get it 100%.
My wife now wants to buy a boxed shelving for the kids playroom - and the first set costs R3.5k - I'm pretty sure I could make it for under a R1k with the right saw.
The only one in the area is Builders Warehouse, in the 10 years I've been here, and requested cutting - they've been operational twice.
