Im after a pair of speed 900's

I dont mind buying brand new if someone can suggest a good source... i found this on an old thread posted by jamie;
http://www.cornwallmodelboats.co.uk/aca ... _6373.html

...but whats the difference between those... and these;
http://www.westbourne-model.co.uk/900-b ... 066-0.html

i know theres alot of fakes going around, and they all have very similar names....

If someone can reccomend a good supplier or confirm one of the above links to be a genuin article id apreciate it.
