I use the Phonobox 2 and Phonobo 2SE. Both are excellent for the money but I have have two Clearaudio ones.
I think the Pro-ject ones are very competent but not exceptional. The RS offers a lot of flexibility but I went for the 2-box Clearaudio Basic Plus which was more even sounding and a better fit with my Clearaudio tables.
If you are running a Pro-ject tables, the RS is a great choice. Add a nice Ortofon cartridge and play lots of records.
