I would suggest people who already have Diskeeper to not join the raffle. There is no good in using Diskeeper and Raxco PerfectDisk complementary since each of them has its own algorithm. SMARTPlacement for Perfect Disk and I-FAAST with Diskeeper. Mixing them both may bring setbacks to your computer. Give the chance to others who has not had top tier defragmenter installed.
I totally agree with you corker.

Great giveaway, good luck to the participants
Please do not count me in.
