I need a ladder for things like painting upstairs windows & cleaning
gutters. I've had a look at various websites, but as I'm not very
experienced or confident with ladders I've got some questions:

1. What's the difference (apart from the obvious) between a double &
triple set. Is 1 more stable or easier to manoevre than the others?

2. I've seen several 'Combination' ladders; are these a good idea -
or a bit of a 'jack of all trades'?

3. Can anyone recommend somewhere to get good advice & a good deal?

4. Are any of the various mats or specialist feet a good idea?

Thanks,

Michael
