Clark,
I have to vote for the RockChucker Supreme. This thing is HEAVY duty. I must disclose that I just bought it and am in the process of finishing building my reloading station so I haven't had the chance to use it yet. However, high recommendations were given to me about this press. Also, I used the Lee Challenger press for about a decade and was told the RCBS is a venerable upgrade. I think the advise given to me so far is solid.
Have you considered sending the Junior in for repair? Then you'd have a faithful backup...
