Anybody use one of these 150 mA LED testers?

I saw one of these LED testers at Fry's Electronics last night, and I almost bought it. It can test LEDs from I think it was 1 or 5 mA all the way to 150 mA. It basically has several rows of holes, and you insert the LED into the holes in hte current range you want to use and push a button. I was wondering if anyone has used one to test LDs? Since it has enough current to lase most LDs we would use. It is similar to this item here:
