Dual channel multimeter or another option?

Isn't it mostly bug fixes from 1.3.9R10 that I don't have in 1.3.9R6? I upgrade slowly and let other people deal with bleeding-edge bricks!
Probe check is a nice feature, but not bleeding-edge. My ancient and primitive TPS2024B has it...

Try it with some different probes and it should autoset the attenuation.

The holidays got in the way but I'm back and still in need of a 2-channel multimeter.
I already have an analog oscilloscope, a fluke MM and a cheap Amazon multimeter. While a DSO is tempting, I was looking for a handheld DMM since they're much smaller and less cumbersome. The Prova 903 looks perfect for my needs but I was hoping there would be an older, used 2-channel model on eBay for under $150 or so.
I'm also in need of a function generator but I'll post another thread about that once I figure out a solution for a 2-channel DMM and just use my computer for a generator in the meantime.

What you want to compare the amplitude of 2 audio output signals, right? And the more these signals are the same in amplitude the happier you are, right? So actually what you want to make visible is the difference between the 2 signals. The bigger it is the more you have to compensate.
Does your scope has 2 channels? If yes it certainly has a substract feature (Inverse + Add is the same). Feed the 2 outputs of the tape device to the 2 channels of the scope and select the substract feature you have a visual that will show you amplitude difference. It will also show you any phase shift between the channels.
Tell us what model scope you have and we can help you out configuring it.
