I owned an X-LPS V3 for a while. It's a nice phono stage, it was quiet, and sounded good in my system paired with a Clearaudio Aurum Beta MM cartridge. Gain and loading settings for both MM and MC are fixed. That's not really much of an issue with MMs, but the lack of adjustability means you won't be able to really dial in the best gain and loading for an MC cartridge.
IIRC, the X-LPS V3 sold new for around $300-$350, so the asking price in the ad you link seems pretty high to me. If you intend to eventually dip your toe into the world of LOMC's, consider the Musical Surrounding Phonomena. The Phonomena has 13 gain and 17 load settings that allow it to be used with just about any cartridge ever made. If you're patient and shop carefully, you can find a used one in your price range. If LOMC's are not currently in your future, then there are several nice phono stages available within your price point. Check out the Musical Fidelity V90-LPS, Pro-ject Phono Box DS, Vincent Audio PHO-8, Cambridge Azur 551P and 651P, and Rega Fono Mini. Or stretch your budget a bit for a Lehman Black Cube.
