There are a few compact digicam which have the wide angles; Panasonic LX3, Canon Ixus 100 IS, fujifilm F200EXR etc...Each comes with their optcal zoom and strengths. It depends on your requirements and budgets.
then lx3 isn't for you. it should be around 700+. also , if you're planning to use it as your only camera , something else would probably be better as the zoom range for lx3 isn't very good.
I've a budget of est not exceeding $500.
