I bought my RDL in a group buy on this forum 2 years ago.
One of the smartest days of my life.
Note: If you find yourself ouside of the maximum number of customers, hang in there.
There's always a few people who get cold feet at the last minute and give up their place on the list.
BTW - I just posted a link to this buy on the forum at IRONBUTT.ORG.
