FOr the bulk of my modelling, I use Tamiya liquid cement. I find their brush applicator more than good enough for the job. It's of quite a good quality, and I've never had problems with it.
I use testors tube glue for large joints. Have testors liquid cement as well, haven't used it yet.
White school glue I use in my dios all the time, and I wouldn't know where I'd be without superglue.
