Lee Challenger with Breech Lock is typically cheaper than the regular priced Partner and you get the quick change Breech Lock. Challenger looks beefer than Partner also. This would be a good price, don't know if a permanent price drop because of the competition from Challenger or a promotion, RCBS' Life Time Warranty and customer service make it tempting while I have a Challenger already. I like my Challenger, which is portable, but Lee Press does not cam over and from time to time I missed a brass not fully sized and need to watch the lever position to make sure die closed completely, RCBS' press cam over, just want a slight cam over for a positive indication if the die is fully closed!
