Sorry - that was wild goose chase - I checked the manual and its a 654de I think - according to the manual. ( I have read the manual but not taken the machine out of the box).
Ebay is totally the place to look for second hand saris theyre really good for it. but Ive found it can be hard to gauge the fabric colours because you're at the mercy of the other persons photo (camera and skills) and then how your screen/eye interprets that colour... having said that Ive got some fantastic saris off ebay. including an amazing full length with all parts black and diamanté one that is so bling!
