I have to agree with @Chetabout it being a tough question! My least favorite is the jigsaw to the point that I typically use a battery Dewalt most of the time.
From there, I actually appreciate most of them just about equally as they are the right tool to get the job done when I reach for them.
Now, with that said, there are some things that I will eventually change in my FT collection.
1. I'll probably add the TS 55. I have the 75 but, it's just a bit bulky for breaking down sheet goods.
2. I'll probably remove the 125 sander as I just don't use it that often. Only really comes in handy when moving through grits and having 2 sanders set up and ready to go.
3. I'll probably remove the jig saw from my collection all together.
4. I have a drill but, only use it when I need the 90 degree attachment. It's a nice drill but, rarely used. Not sure what I want to do here! Leave the situation as is or switch them all over to only have one battery charger.
What's holding me back from making the wanted changes? Mostly the storage I have for these items in the shop. It would force me to reconfigure the storage space I have and I haven't done my homework to know if I'm removing enough to equal what I want to add.
Great conversation topic!
