OK, you're looking for something in the middle then.
For parallel protectors, LEA CFS or SP series, or Transtector Apex II, may
be more in the price range you're looking for (under $1000). Since I don't
use protectors of that kind regularly, I don't have any other
recommendations other than to stick with repetuable manufacturers and read
the data sheets. The cheaper ones will probably be MOV-only. Others may
use a combination of MOV's, SAD's, and/or gas discharge tubes. There are
pros and cons to each...
I don't know of any series protectors that fall into the price range of what
I would think you're looking for.
Someone else (Eric?) mentioned Square D. The only Square D ones I've used
are the ones that are built into the panel (Surgelogic or something like
that?), not the add-on ones. We had to replace one in a 3-phase 480/277
panel not too long ago, that's the only reason I'm familiar with them (they
have an audible alarm that goes off when the arrestor detects a fault, a
nice feature).
