Purple Ti-10 yes, quite a few in HK in various shops(valid from last week.. hehe) MP-99 2U... some place, rare though, forgot where already... MP 100, don't remember, don't think so. for MP 99 2U G5, I personally know a friend has a brand new and haven't used, if you are interested, pm me, maybe I will ask him to see if hes willing to "let go" haha.
I saw and I held it in my hand and compared to 3U... it is heavier of course haha.. usually 2U ti-10 purple is more exp than its 3U counter part. 2U should be available everywhere although they keep saying it is rare. "e78" for sure I saw one hanging, 2U purple.
