In general, I usually tend to look toward pres with tranformer inputs when using mics with transformerless outputs; such as the M147. Maybe something like a Neve 1272 or 1073.

On the other hand, I tend to look toward pres with transformerless inputs when using mics with transformer outputs such as a U67. Maybe something like a Buzz Audio MA 2.2

I MOST definetly recommend the Distressor.
http://www.empiricallabs.com A very nice mono compressor and VERY "warm" indeed.
Now with the above said, if you were to use the M147, either Neve, and the distressor in the same chain, you MIGHT find that too "dark" for MOST things; maybe not.
So if you were to use a either Neve pres, you MIGHT reach for a more "transparent" compressor such as the RNC by FMR
http://www.fmraudio.com or the likes. Or if you were to use a distressor, you may choose a more "neutral"/"in the middle" pre such as a Joe Meek
http://www.joemeek.com pre or the likes.
That is of course, IF you decide you need a compressor at all. If you don't have a "decent" one, though, it's ALWAYS a good idea to keep one close by for when you need it.
Another idea I might suggest for a EXTREMELY versetile set-up (which is usually an important thing if don't have many "decent" pres and compressors) is a DaviSound TB-3.
http://www.davisound.com It's a stereo solid-state pre and stereo tube/solid-state compressor. Meaning you can either have the tube in the compressor circuit or not.
Just some suggestions...
