Hello all. I'll keep this short and sweet. Im seriously looking into the digital SLR world in hopes to purchase a remarkable machine at a relatively decent cost. [Note: i realize "decent" is quite the arbitrary term associated with finance these days. ><] Anyways, my question for you is this - which do you think is ultimately key in deciding on an epic photo device: higher sensitivity [ISO] or larger scale Megapixel? Again, lets assume we cant have both - in hopes to lower expenditures. Please. Enlighten me!
