it's also best to wait for low price start as well, also major japanese companies such as book off use japanese yahoo auction to see things
my purchases from yahoo auction via buyee ( inclusive shipping cost to hk)
xba-40 quad balanced armature brand new, sealed, cost in HK, around HK$2200, purchased for JPY10000 (HK$700)
special limited edition leather case by japanese saddle maker for walkman nw-zx100, called CC-ZX100, sells on ebay for US$150, purchased for JPY4500 (HK$315)
psp 1080p upscaler and hdmi processor, cost on ebay around gbp60, cost JPY4500 (HK$315)
In the meantime, I got a MC Zenitar 16mm f2.8 fisheye lens on the cheap. Works well for my needs and just playing around with the distorted view.
