I didn't word my last post very well. What i meant is that Scythe's FDB fans are (typically) OK, as is the FDB stuff by Noctua, AC and (probably) Noiseblocker.

They're still not good. FDBs are...

:lol: thanks. I almost wired it up without using the perfboard, but that was too sloppy, even for me. :D

Well, I ended up ordering a number of the Peak meters and a B&K 830. I think the 886 is too expensive for the use I'll get out of it for right now. I think the Peak gear will end up being very useful...

Well, we're finally making progress.

Well, I got my differential probe and my capacitors in today.

At the $300-$500-550ish range, I wouldn't go Canon. (OW, typing that hurt :D)

I would not recommend the D200. It is an extremely old camera and my experience has been that digital camera sensors...

Aside from the good glass part, you're absolutely correct. There is no <$500 camera that has decent glass.

That was my assumption. Still seems like something of a cop-out to me, but my expectations might not be reasonable. :p
