For GENERAL photography a relatively inexpensive meter such as a Sekonic L-308B is great - I have one of these and also a Sekonic L-358, which is just a little larger, more robust and has some additional functions which I never use. However, as another contributor has remarked, night shots are something else. The only real way to meter these accurately is with a spot meter - meter the highlights and give 2 stops more exposure. As the bright parts of night scenes can be small, the spot meter needs to be a "real" one (1°) like a Pentax, for example, and not a regular meter with a 5° attachment. As the level of lighting of buildings at night does not vary all that much, you could do worse than start with the exposure recommended above and bracket exposures slightly either way (cheaper than buying a meter if you would use this only for night shots). As regards Fred Parker, he has his admirers but I am not among them!
