I won't have time to work on it this weekend so in the meantime, does anyone have a preferred brand of radiator stop leak that I could try to hold me over?

If the aluminum core is leaking, I'd try Barr'* stop leak. I haven't personally had success with the powdered aluminum varieties, but maybe that'd work for you - it depends on the size and location of the hole.
If your radiator has the plastic end tanks and that'* where it'* leaking, it'* time to buy a new radiator

Not a fun thing to find out, but an opportunity to upgrade at least.

Don't use stop leak! A lot of that stuff on the market clogs up your cooling system, especially your heater core! (aren't those fun to fix
) Anything stopleak is bad for your car whether its P/*, transmission, and A/C. I won't do A/C service to a car with stop leak in the refrigerant because it clogs the filter for the A/C machine and it won't work(older) new ones won't even let you service the car. The only coolant stop leak I have had be ok is the GM brown tabs that you smash with a hammer. If your gonna replace the radiator just keep topping it off, its your best bet.

Stop leak doesn't always cause a blockage or problem.
Most of the time it'* fine and does the intended purpose. In extra doses by the uninformed is where most of the problems happen. It'* like adding dye to an AC system. That doesn't clog or cause an issue...it helps you fix the issue.
