I have had a KD-7000 scale since 2016 and it still works great. I bought the adapter as well so I don't have to use batteries. I also have a less expensive kitchen scale we use in the kitchen and out of curiosity one day I tested to see if there was any difference. The less expensive scale was just as accurate. I do like the KD-7000 for it's capacity and the fact that a large bowl or bucket doesn't make it impossible to read. You can probably learn to use any stick blender effectively, but after having one with a high/low speed option I will always look for that. I've never found one at a thrift shop. But now that
@Zing has mentioned Buy Nothing, I should put out a ISO post there to see if anyone has one they want to get rid of.
Because most of the other things (bowls, spatulas, etc) has been covered, these are the tools I saved for (once I knew I was going to stick with this obsession). You don't need any of these things, but my favorites in the order I bought them are:
1. A silicone lined wood mold. I bought my first one from Nurture, and it is still my favorite. I have gravitated to the tall & skinny profile rather than the loaf though. My favorite T&S is also from Nurture.
2. A wire cutter. I was so frustrated with wonky shaped bars that this was my second big purchase. I ended up selling my first cutter and bought the Polaris from Custom Craft Tools. It's an investment, but worth every penny to me.
3. A soap planer. There are lots of options out there. If I get ash, it is only on the tops of my bars and it drives me crazy. There are ways to remove it, but it's so easy to just plane it off. It can also pretty up a side if you happen to unmold too early and the soap is still a little sticky.
