Get a 10x stereo lighted scope. If you can afford a second magnification, maybe something like a 10x and a 30x. The 30x you won't need very often though.<br>

I’m 67 with bad eyesight and not so steady hands, but I guess it’s time for me to learn how to do SMD. Any advice for how to get started?<br id="lineBreakAtBeginningOfMessage">

But you'll need a SMD to DIP adapter. None of the modern opamps are available in DIP</div>
