I really like the Model Master 'Liquid Cement for Plastic Models'. Although the pure liquids (e.g. Testors) are fine when the parts fit perfectly, I really like the Model Master stuff for it's gap filling properties when the fit isn't exactly perfect. I've been using it for decades.

Well, I'm running low and was looking to buy some more, but apparently it's been discontinued. Worse, the similar Testors stuff has also been discontinued.

Does anyone know of a good alternative?
