If you are really shooting in low light then your problem is not which meter, but how to meter.
Take a typical example, a street at night where the sources of light are street lights and shop windows. If you meter the overall scene you will produce a long enough exposure so that the street itself will look like it was shot in daylight while the shop windows and street lights will be totally washed out. If you meter the shop windows then you don't have a low light situation, they are bright.
In this case you will get well-exposed shop windows and the rest of the scene in darkness. This will parallel what one would see in person. Similar situations occur with landscapes or seascapes at night or dusk as well as dimly lit interiors.
Metering is designed to make the scene look "normal" and this may not be what you wish in most cases. There are several guides published (and online) which give average exposures for typical situations such as these, I suggest trying these as a starting point.
The meter in my Pentax 67 goes to about 4 sec at f2.8 with 200 speed film. This is good enough for a brightly lit street at night. Beyond this I just guess. What's the worst that can happen, you waste a few extra frames of film?
How many frames will you have to waste to pay back the $200-300 a meter might cost you?
