From a stand point of feeling good about being in the club I would say to spin it again. There are 2 ways I see this working for both you as the runners and us as the members.
1) Spin again for it in 2-3 months following the miss, this way you can have a bit of safety time padding around some of the bigger/intricate builds.
2) Replace one of the mid-month console spins with the PC. This method maintains the 1 PC a month average rate and if you get to the point of high/low rollers then the second chance draw can be extended to the low rollers.
From a loyalty point view, I'd say any of the methods are good. Unless a person holds a large number of loyalty points then auctioning it wouldn't matter to them. I'm not sure how the split of points looks across all accounts, so that would be some data you could consider. Doing the auction might incentivize some people to buy more points though, so there is that to look at from a business model as well.
