My brother has a Voicemaster Pro. It's okay, but not great. There are better out there.
The thing about the Voicemaster Pro is that it has a lot of features, but to me some of them almost seem gimmicky. Using my brother's Voicemaster Pro, I felt like I got the best sound out of it when I disabled pretty much everything except the preamp.
So if that is the way it is going to be, I'd rather own a channel strip that has just the basics, but the basics are really good. Or even just a preamp without any other features, but just a really good preamp.
If you are looking under $1,000, I'd say take a look at the Safe Sound P1. It has a compressor and limiter built in.

Here are some that are preamps only. What you would do is follow them with a compressor if needed. So basically, you build a channel strip out of separate units.

There's
the Summit 2BA-221:

Also worth a look is the Groove Tubes BRICK;

I know you mentioned channel strips specifically, but in the below $1,000 range I think you might get better quality buying a preamp and the compressor/eq sections separately. Most of the "all in one" channel strips in that price range are compromised in one way or another.
On eBay there are some great compressors going for not much money. One in particular is the Aphex Expressor. There are basically two versions of it, the older 651 and the newer 661. These go for between $150 to 200 or so, which is stupid cheap for what is a great pro quality compressor. The Expressor is a full featured compressor that works very well on voice. One of the preamps I mentioned above followed by the Expressor would be a great channel strip.
Another compressor I personally like that's a couple hundred on eBay is
the DBX 160X and the 160XT. Not quite as versatile as the Expressor, but very commonly used on voice, and again a fine pro compressor, not a toy.
So there's a few extra thoughts for ya!
