Its actually more important to match the phono stage to the cartridge you are using, not the TT. So in this case an Ortofon 2M Black. Being a MM cartridge, you want to find a phono stage that has as selectable capacitance as low as possible to at least 100pf. Most fixed stages are at around 200pf. Some standouts within your budget that I can think of would be...
Lehman Black Cube
Musical Surroundings Phonomena II
The above would be a good place to start.
A friend of mine uses the IPhono stage with stellar results in combination with his Scout/Zephyr. Well worth the $$. Smack in the middle of your price range.
Sutherland seems to be a good one and receives nice reviews. The Insight is $1500 new I think however, $950 seems like a good deal. Do you have experience with Sutherland Yogiboy? What is the sonic signature? I'm more of a tube guy so I don't like the cooler side or front row but also don't like too warm or back row.
I had access to a battery operated Sutherland that cost 3k new. I compared it directly to a Musical Surroundings Phonomena I ($1200) in same system.
Based on what you like you would like the Sutherland. It had more of what people would consider a typical tube sound. Warmth, smooth, not as upfront and not as tight bass.
The phenomena was much more upfront with tighter bass. The Sutherland was a bit better at separating voices from the mix a tab bit quieter. Overall different presentations. That being said the Sutherland edged out the phenomena but considering the price difference the phenomena did very well and was not blown out of the water.
But again a Sutherland is more of the sound you may be going for.
