Are you person who keeps his tools well maintained? If so, save and buy a CR.

If you only clean your tools when they aren't performing, buy an Eclipse.

My reason for saying this is that the eclipse uses a drop-in, tapered seat style nozzle that is much easier to remove, clean and replace. The body of the brush is very easy to clean as well. So when you finally do clean an eclipse, it cleans easily and completely. The screw in tip of the CR may have you cleaning less often than you really should.

just my .02, and I own 2 HP-CS's and an HPC.
