I guess I would agree with BunnyLakes here. I'm sad I've missed several group buys (this one included) at this point (due to financial reasons/timing), but I guess that's what makes the classifieds section, group buys section, and the community as a whole so appealing to me.
With the classifieds, I've seen sets up for sale and typically at cost or even less. Sometimes, yes they will be at a premium, but that's the cost for not joining the GB and showing your dedication for purchasing that set. Yeah, you might not have been a GHer when the gb was active, but now you are. There are plenty of sets to be had in the future and I think providing options allows for a more diverse community. So if your interested in a old set, check out the classified section - someone might be willing to part with theirs.
In terms of the group buys, I'd really like to see different sets coming out versus repeats. These group buys take a long time to put together and frankly, if you go for something because it catches your eye, that's your choice. Your rewarded with having the set. The point of the gb's aren't to create envy or to sell at premiums. If you didn't join the group buy and decided you want the set later, refer to the classified!
Tie all of this together and you'll realize this is exactly the reason why some people are a part of this forum. (not necessarily me)
