Out of the three bears Issy is lasting the longest. I think Cheery is a really nice bear, one of the nicest for a long time. No Nectars at all but luckily got one when it first came out.
Bit hit and miss with Unity.
Managed to find a couple at almost retail but bought a couple at 20 as well. I have made an effort to get them though. No walking into the shop and there they were type situation. I offered up a Buck buddy and Unity beanie for a Sakura beanie and had quick replies from Japan, so obviously they are still in demand over there. My opinions on surface mail are I would not wish to trade using that.
