Raffling Ipods and Accessories

I can’t give out that many Ipods to my outstanding call center employees but I can also add Ipod accessories in my monthly or weekly raffles. Not everyone uses an ipod but a lot of them do. Those who win ipod accessories but do not own the main unit can always trade with interested coworkers or sell it to them. Of course, I also plan to raffle off other phone accessories and the winners can just swap prices. What do you think?
