Hmm, what do I have so far:
About 40-50 hobby paint jars (either MM, Tamiya, Humbrol Acryl or CItadel)
20 or so spray cans.
10 tubes of artists watercolour paints, Grumbacher (I use these for washes)
Some pastel chalks and weathering powders.
20-30 brushes, including small sable detail brushes and corase, large area brushes.
4 bottles of poster paint (2L each) in Brown, Black, White, and Dark Green. I use these for a basecoat on dios, as they're plentiful and cheap.
One pair of sprue cutters (need to get another, good pair)
Various pliers (prob 10 in all)
Sanding sticks and 3 rolls of general grain sanding paper.
Knives...lots of them. About 10 knives (different types of handles) and about 20 spare blades, most the standard cutting blade.
A half-used jar of Tamiya Cement plus one new jar of said cement.
One jar of testors liquid cement.
2 tubes (one almost empty) of Testors plastic tube glue.
1 tube of Testors filler compound (comes in a gray tube, same size as the orange glue tube)
2 full and one half-full bottles of white school glue.
One spray can (full) of spray adhesive.
Thinners of various kinds and brands.
Airbrush and compressor.
Two spare part boxes, used for differing parts. One is an old running shoe box that I use for medium to large peices, and the smaller one is the M26 recovery vehicle (dragon wagon) box for small parts, currently about to fill up.
Outside of that, I have a plethora of other things that come into use at different times, anything from rubber bands, popsicle sticks, to a bandsaw, clamps, wood, wire, mesh, you name it.
And waiting for all those to be used are 20-30 unbuilt models.
