I bought my Canon SX10 IS for the same reason as u.... gives me flexibilty in setting, shutter, apperture, exposure, etc and comes with equivilant of 20x zoom... but price wise way off ur budger, brand new abt $700 i've seen 2nd hand abt $500
wow tight budget yah. canon tend to have some manual control in their cameras but they have a tendency to exposure only up to 15 seconds.
lx3 is the king now, followed by the fuji f200.
but at 200 you might have to get something like a powershot g6, some technicals f2-f3 . 35mm-100+mm equivalent i think.
i saw people selling some sx100 for as low as 200+ abit, but that one is more for fun i think. 36-360mm i think. i played with the sx110 in the canon shop, very fun, but have to stick to iso100 or 200.
