If you were to look at my modeling desk right now
you would find the following:
A - Super glue (thick & thin) for resin, metal, reinforcing parts and the occassional small part that I don't want to hold in place for 15 minutes.
B - Epoxy for the same reason as A but when I need a little longer setting time for proper positioning
C - Elmers white glue &/or Krystal Clear for gluing clear parts together and attaching canopies
D - Liquid cement for the bulk of my cementing
(I started out using liquid cement in the 60s, with Pactra being my favorite (think I still have a small bottle of it squirreled away somewhere down there). When Pactra quit producing liquid cement went to IPS Weld-on 3. I sometimes tend to try to find things cheaper and lucked out. When Weld-on 3 became scarce in hobby shops found a product at a plastic supply shop in Topeka called Pleximent (or Pleximent Chloride), which turned out to be Weld-on 3s bulk source. Weld-on 3 was $3.95 for two ounces back in the late 80s, while a quart of Pleximent was $4.95. The quart is no longer avaiable but it can still be bought by the gallon (I just ordered a gallon for $26.95). A quart of that stuff would last me 1 1/2 to 2 years. Might see if any of your buddies want to go in with you to help you defray the cost.)
F - Walther's Goo for those occasional items that need to be fairly well secured to allow them to be worked on but then need to be removed for one reason or another prior to final assembly - also very good for securing figures to a base for painting.
Oh yea, I still keep a little tube glue around and even use it on occasion
