In no particular order:
- Boston 2612 Paper Cutter. I got this at the Goodwill Outlet for $2. They go on ebay for around $40 plus shipping.
2. Scotch Thermal Laminator. You have no idea how happy I was when I got this a couple years ago. It still works good and it's so easy my kids can use it. It's nice because you can print worksheets you may use over and over again, and just print it once, laminate it and use a dry erase marker. Saves paper and money.
3. Metal Baskets. I have three different sizes and rotate what I put in them. Here is one with some flash cards.
4. Ibico Kombo Plastic Comb Binding Machine. This was a steal. I paid $30 at a thrift shop a few years ago. They can go for about $250.
