Big jump. The DB Master is quicker, probably lighter, and should be better equipped.

Some say the Master compares to the Ironman, but my guess is it compares more to the Schwinn PDG Series 3.

The Masters I've seen that were not OS-tubed were nearly identical to the Lemans RS by Centurion. The yen was climbing so fast, they had to drop a level or two of components to stay in a decent price range, but I'd still say the Sport DLX was probably a step down from a DB Master.
