I´m on a shoestring budget and have opted for a free iphone app. Works great for me altough rainy weather will be a problem since the iphone isnt very happy about wet weather. Its probably not as accurate as a dedicated meter but you quickly learn how to get around its shortcomings. That said, i will get a dedicated meter down the road but right now i prefer to spend the money on film and chemistry in order to get my work done. I have also found that the "sunny 16" rule is surprisingly accurate once you get your eyes tuned to compensate for various lighting conditions.
