Yeah, I'd take that Speck or Langevin ANY day!!! Other's I'd take ANY day? DaviSound TB-4 or API 550b (upfront, it'd be more expensive than your budget due to the cost of a rack/PSU like the OSA version, but well worth it for future purchases of pres and comps).
As an alternative, I'll sell you my fully discrete original Trident CB9066, single-channel 3-band parametric EQ with sweepable Qs and one sweepable high-pass and one sweepable low-pass filter.
I'd sell it ONLY because I don't use it often enough to justify keeping it around... My production style for the most part is: If I can't do what I want with what's available onboard, then I need to rethink my mic positioning, mic choice, or mic/preamp combo choice! Ya, there will be times I miss it and wish I had it, but it makes more sense for me to take that money and invest it into something I'll use a lot more often and in something where my setup is really lacking and would benefit from some improvement.
