Medical supplies for tools- Check Ebay's Medical Supply section for deals... Practically any medical supply store will have the tools you're looking for much lower prices than any dedicated hobby supply store or online hobby store. ESPECIALLY for things like pipettes, syringes, scalpels, & blades. It doesn't hurt if you have a friend that works in lab either... I got a gal at the local hospital that I buy lunch for now and again and she gives me BOXES of pipettes and specimine cups for mixing resin, RTV rubber, & paints..
Glues- Testor's Liquid (Pink Bottle), Testor's Model Master Liquid (Black Bottle), CA - The blister-pack tubes you find in grocery store school supply sections that are 4 for 1.99 or the like.- White glue, off-brand will do nicely, (Note on Testor's Pink bottle: Throw away the brush applicator in the cap.. It's useless. Apply it wth a decent #0 or #1 paintbrush) Applying CA is best done with a sewing needle that you've nipped the top off, making a two-pronged applicator... Straight pins that have the points nipped off work well for applying tiny amounts in tight spots. Put them in you pin-vise.
Paints: Hobby shops for certain military FS colors. Craft stores for acrylics... Many of them are the same as military colors, they just have those goofy, "chick-name" for colors... For instance, Anita's "Mushroom" is a pretty good match for Tamiya Khaki Drab. Plus, they cost about 1/3rd the price of "Model Shop" brands like Tamiya, Model Master, Polly S, etc., and you get twice to three times the amount of paint. Most prices start at .99 cents for a 2-Oz bottle of something like "Anita's Craft Paint" vs 3.49 for Testor's MM 1/2 Oz.. Take your color chips with you and compare... Hobby Lobby has an EXTENSIVE selection of these types of paints back in the Craft Section... You get a great selection of rattle-can paints back there as well, 10 Oz cans vs. 3 Oz. of MM for around 2.00 to 3.99.. For blacks, whites, and primary colors in flat & gloss, they can't be beat, and the metallics are cheap too... Straight silver or aluminum as well. Same goes for clear flats and glosses/semi-glosses...
Auto parts stores for paint and building materials as well like Bondo red Glazing putty, Bondo auto-body filler, spray paints & primers, etc.
It also helps to have a friendly Hobby Lobby manager as a contact... I "tamed" mine by suggesting a display area in the store for modelers to show their completed work of kits purchased at HL.. She'll now stray from the "Company Book" at times, ordering kits for me that the warehouse has, but aren't on her store's Stock List.... One lat thing about Hobby Lobby... USE that 40% off Coupon every chance you get... You can use one per day, and if you're slick and have time, twice... Three times if you got your wife with ya...
Just be sure to make the second trip after shift-change at 4:30 so you get a different cashier, lol...
