New diy'er in a world of op-amps

[llamaboy]

Hi all, I'm pretty new to all of this, and I hope to not be new to it sometime in the future. I've been sampling a lot of op-amps from TI, have National Semiconductor's best (LM4562), and even have one coming in from Analog Devices (who are a little on the stingy side compared to the others). I'd like to find some of some other manufacturers, and am putting together a database of op-amps, voltages, and sounds based on what I receive and hear.

I have a couple questions about this subject. I put some in the newcomer's forum but was informed it would be best to go to the respective forums, so that's what I'm doing.
First up is military-grade amps. I know they are tested to work, each and every one, and have other certain processes for ruggedization. Most of this, based on my experience with military avionics, is a lie, but does anyone have any experience with military op-amps, like the TLE2142MD? I don't want to put it into something unless I'm sure it will work, so I need to pull up the spec sheet from TI sometime tonight, but I have the swine flu (no joke--it sucks) and am feeling really lazy, and would rather have people give me opinions.

Next is something that I've had for awhile, and does okay I suppose: the Boosteroo. It's powered by a couple of AA's, for a total of 3 volts. What's the best op-amp for this situation? I know the OPA132 isn't; already made that mistake. Gonna be a pain to get out.

I'm wondering a few things about sound cards, but I'll stick that elsewhere.
