I stumbled upon this Riseman on e-bay a few days ago, and have been considering making a bid. http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&rd=1&item=350142824116&ssPa geName=STRK:MEWA:IT&ih=022
I already have a MIY Riseman, and have just noticed a few problems with this one.
1 - Module 1663 (MIY Riseman has module 1664)
2 - The 2 coloured spots a 9 and 3'o clock are green and blue (MIY Riseman are both silver)
3 - The buttons are silver (My MIY Riseman has 3 grey and 1 yellow buttons...(?))
On looking on Risefreaks page below
It looks like the seller has changed the bezel and band off a DW-9100B-2AV.
Although it would still be a good buy, i thought i'd just give anyone a 'heads-up'
