Diver down under flag and reel

[Scubasleep]

I am going to buy a diver down under flag and wanted to ask a few things.
Which reel should I get to go with it, pro's & con's of them.
I also wanted to know what it is like to pull a flag around while your diving? Is it a lot of work to pull all over, or not.

Also If anyone has a used reel that they want to get rid of I would be interested in buying one.

Thanks
Joel
