I look at Hobby Lobby. They have good prices even without using the coupon. My best sprue cutter came from there. It works great, and cost about seven or eight bucks. You have to peruse other sections. I find a lot of tools in the beading section, and good prices on brushes in the painting section. They have diorama figures in some scales, and trees, grass material, etc.
I recently started using a little mini hand grinder I got a few months ago from Michaels in their beading section. It was on sale so cheap I took a flyer on it. It only takes 3/32 tools, but I had some, so I tried it. I need extensive hand grinding work on my current build and it works great. It was under thirty bucks even without a coupon, and weighs very little- comfortable to use. Michaels also has good prices on brushes.
