My neighbor gave me his old UEI DL250 <broken> and I looked at it for a minute. Pretty much 2 cards, a display and some switches that tested good. I gave up and fired UEI an email. The deal is $25 and shipping, I got a new one. (says it is rebuilt). Since the cards were bad the display scratched and the case broken I can't imagine what they saved.
I assume most name brand guys do this but I was impressed.
Pretty cool meter too. Clamp with all the regular multimeter scales and a capacitor check scale.
