I am looking for a computer with a backlight. The LBS was no help. Any suggestions?

Handlbar mounted light designed specifically for that purpose. Works with any computer.

I used a Cateye AT-100 for a long time. It had a backlight, but it stunk.

It was one of those Electro-Luminescent deals, so the lighting was even, but contrasted with my headlights, it was dim and I really had to zero in on the display and look hard to read the numbers. On top of that, it was on a timer, so one press of the backlight button would get me maybe five seconds of time to read. And lastly, if the batteries were getting stale (this particular model needed a new battery twice a year), it would crash the whole computer. Blooie!

I've since given up on backlights, because even if the thing stayed on for 30 seconds or a minute, I'd probably eventually wreck trying to read it while riding. Plus my helmet lamp has eliminated the need.

Be nice to hook up a small, power-miser LED to a headlight to use as an aux computer light. It could stay on all the time, provice a useful amount of light to make use of the display with a quick glance, and would barely tap the battery. Now that I think of it, it's be pretty easy to rig in line with a typical Nightrider setup that could easily be unplugged when not wanted. Hmmm...

If you like the computer you have now, there is no need to get another. The Sigma Sport computer light mounts onto the bars next to the computer and lights it up.
It was $10 a couple of years ago.

For $10 (about) you can buy The Sigma Sport computer light.

For a while with my Nightrider light I just used a fiber optic filament. One end pointed at the lens and one at the computer. No power drain, Good lighting. I used many different ways of making it look good. It always looked unfinished. After a while I realized I did not always want to see the display, so I took it off.
The nice thing about the Sigma Sport computer light is that you can turn it on and off. I just like to read the mileage on a century in the dark once in a while, or see what time it is. Then I keep it off. I think one battery will go three hours.

I finally realized that if I hold my white water bottle in front of my headlight, even while riding. I can see the computer and anything I want to. Even the pedals. Anything. Even a hand works pretty good.
So I have no need for a computer light, I can see it anytime I want to without one. Just need a water bottle or a hand. I usually have both.

Less is more.

just for the reason mentioned above I have a surfire tactical flashlight I take with me that runs off 2 Lithium batteries @ 6V making 120 lumens....it's uber small and has a holster, I love it.

did you ever play with the one mounted in the stock of a shotgun?

Remington 870, tactical model...yes.

Me too, same one.
