It is much easier to find MM than MC,
Rogue Audio sphinx v2 is well regarded.
Options open up used, but phono in integrateds is getting harder and harder to find.
For an excellent, cheap solution, if you like you current amp, try the Schiit Mani - it is a $129 SS phono stage, that simply does things properly, it will not let you down. IMO.
I have not heard it, but Rega Brio - R gets some love on the affordable end.
