My purchase list for my new lab -- budget $1000+, thoughts?
rstofer:
I use the OptoVisor for most simple things but this visor is a LOT cheaper and more featured:

I bought it a year or so back and I really like the lighting. It tilts and swivels to put the light right where you want it. Highly recommended.
I don't like the loupe, I lose stereoscopic vision and it just seems awkward.
I think there is a discussion on microscopes over in Test Equipment (?) and I think the conversation gravitated toward:

I don't have one...

Which Optivisor model do you use? (there are apparently a variety of focal lengths / multipliers)
DA-4 seems popular from what I am seeing (2x mag at 10" focal dist)

That's the one I use. I also bought a more powerful lens and it works ok but the focal length is so short that I hardly have room for a soldering iron.
The DA-4 will work for SMD but I prefer a little more magnification. Not enough to buy a micrscope...
The one I linked has two lens assemblies of 1.9x each so nearly 4x. One of them flips up inside the housing to get less magnification and more focal length. I have only had it since April so I haven't played with it much but I think it will work a little better for SMD.
For $10, it's hard to go wrong. That's about 1/4 the cost of the OptiVisor that has no features.

I have a dumb question that just dawned on me.
What exactly is the purpose of buying more leads if we already get some leads that come with our multimeters?
tooki:
Multimeters come with probes, occasionally with some other terminations (alligator clips, etc). But the pack-ins are usually much too big for fine electronics use. Plus you need leads for other stuff, like connecting to a power supply.
I find that I use banana-to-minigrabber cables a LOT for both powering and measurement. Also, banana-to-header ("dupont") cables I make, both male and female, for probing and powering breadboard projects and projects on PCBs. Both of these types of cables are good for powering and for monitoring a value over time, whereas probes are good for when you need to take lots of measurements of different spots in a circuit. And you can often combine both, for example a banana-to-minigrabber for connecting the negative to ground, and a probe for the positive for measuring all over. Keeps a hand free.
Banana-to-banana are also essential.
