Pro-Ject Debut Carbon EVO or Rega Planar 1 or Music Hall MMF-2.3 for casual listening?

Thank you to all those who have responded.  I've decided to go with the Pro-ject.  It is currently on back order and I'm just waiting for it to be shipped. 

Whatever you get,  an appropriately priced phonostage can possibly make your experience more pleasant than the internal in your preamp.

another vote for the Project Evo.

Of the 3 you mention, I'd go with the Project Carbon EVO. 

Look at the excellent Pioneer PLX1000. Add a Nagaoka MP-110 cartridge. And as the records sound like they need a good cleaning,  a Spin Clean.

I know it's a little over budget but you'll get a sturdy machine and you can upgrade the cables if desired. You might even start collecting a few more old records from stores.

On the other hand, if it really is to just hear the ones you have a few times, and be done with it, the inexpensive Audio Technica LP-120 with a cleaning machine bundle for low money may be all you need.

Only one man's opinion:

1) Music Hall

2) Rega

3) Pro-ject

Have you given a thought to the cartridge? That will make a much bigger difference

in sound quality then the sound difference between the above tables at that price range. By the way, I own the Rega 6 with their Ania cart. and I'm happy with it. Music Hall Was actually my first choice, but the Wife Factor kicked in. I also have a mix of old and new records which I listen to only occasionally.
