Comment That depends on what you do in and with your room (Score 1) 416
It is interesting to read people's responses. A lot of people don't seem to get that we don't all do their job. I would never buy a soldering iron. I suck at soldering and, at my hourly rate, it would be criminal to bill a client for having me try to fix something.
A few things that I have found.
A headlamp is generally better than a flashlight. You can take a headlamp off and use it as a flashlight, but it is a lot harder to mount a flashlight on your head. I have a great big thing that is designed for construction workers. I look like a fool when I wear it, but it works great.
The "network testers" that are really continuity testers annoy me. They cost a lot for not much information. I use a Byte Brothers Real World Certifier. http://www.bytebros.com/bb_pdf/RWC1000K_Real_World_Certifier_RS.pdf It gives you a lot of information for not a lot of money. Their LowVoltage Pro looks even better, but I haven't ever used one. I don't know what they mean by "pass/fail" on the cable test.
ifixit's 54-bit driver kit is nice to have around. http://www.ifixit.com/Tools/54-Bit-Driver-Kit/IF145-022 It doesn't replace real screwdrivers, but it is always there when I need it. I'm embarrassed by the number of times I have used the #2 Phillips out of their kit because I can't find a real screwdriver.
I believe in PC attached label makers. I am much more likely to label things when I don't have to find the labelmaker and type on a chiclet keyboard. I still have a Brother 1500pc, but there are current models. Get one that does 1" labels. You don't use them often, but when you do you are happy to have them.
But it all depends on what you do. For me, a USB to PATA/SATA adapter and an external power supply that will spin a HD is invaluable. Maybe not so much for you.
