I just use Testor's Liquid (Pink Label), or Testor's Black (needle appicator)... For the times I need a "hotter" cement, I use straight MEK (Methyl-Ethyl Ketone, but that stuff is getting hard to find)... MEK is a primary ingredient in most of the liquid styrene cements anyway, Testor's, Tenax, Weld-On, etc ... Add to that that a quart of MEK will probably last you a lifetime, and costs about the same as two 1-oz bottles of model cements...
