Quite a few of the tools available on bonsai sites have equivalent tools from local sources much cheaper. Soil scoops for $20 or so or measuring cups for $2. Brushes for $30 or vegetable brushes for $5, etc. Tool carriers the same.
The wire cutters that snip wire off aren't available anywhere I have found here. Soil sifters might be replaceable with something, but I tried several things and gave up. Concave cutters aren't available here. Little bitty snippers are just scissors; I have used old fingernail clippers pretty well.
Look at the function you need to perform and see what you can get for a reasonable price. There was a video online of a motorized soil sifter, four cylinders of chicken wire of different size that rotated dropping smaller and smaller pieces and finally sifting out dust. That is probably more than you want to do.
