I asked CP about this a couple of weeks ago, and they said they're no longer stocking the UZi since it's discontinued. Apparently it's the same situation at AP too, though I haven't checked it first-hand myself.
I'm planning to get one after I leave for USA next month. Looks like the eBay prices for a new refurbished C-2100UZ are marginally cheaper than local retail prices anyway (which are around S$950 or so? or at least this was when stocks were still available).
