Yeah, the release cycle has been discussed a few times before. the LL/LL2 is the only amp with an MKII that was a little short and differences were minimal, everything else has had a fairly normal schedule. Its up to the customer to make buying decisions based on resale value. Personally, I list that as a factor but buy what I think I'll like.
By the way MH just so you know, the LL had a good resale value - you are the 5th owner, and each time it was sold it sold a little less as people didn't want to flip. To an untrained observer of FS listings, there are "all these LL's for sale so cheap" when in reality it is the same unit selling over and over. LF seems to be supply and demand, there are a lot of LF's out there and the high-end market doesn't seem as busy as it once was.
