Totally agree meters are cool, and tho LEDs can be 'more helpul' for displaying pre & clipping, and even amp gain matching, with mulitple (different mfgr) amps they can be really distracting (but sometimes also very entertaining for 'dialing up the blinky lights'!).
Sure I could defeat the leds (on some of the amps) or tape them over, but sometimes want to use them.
Next step is to build a custom rack for the amps, perhaps with a door to control the 'blinky stuff' distraction.
My listening position is also farther away from my amps than it used to be, so 'readability' might be an issue with many of the finer looking VU meter needles.
I looked for standalone meters like yours, but wasn't successful (at least at a price I could tolerate).
So I got one of these:

I got as far as testing it out, and it IS way cool, but has fallen down in my priority list to complete a cabinet for and wire it up..will have to wait for winter months, now.
A good 'cheap but very interesting project', but behind another 'pricey but very very cool' project also in flight (or two, come to think of it!).
Almost hoping for a long cold winter this year!
