Hey
If you are from the U.K then i could post you a couple of those connecyors as i have a bag full of them. Alternatavly you couldhead over to www.hyupjininc.com wher i got the connectors and request samples (I just said it was for a project and the nice guy sent them by next day courier from korea to england free of charge!)
Just go to that site and type in '3050' in the search box and then click on the top connector on the list, then click on 'request sample'
Good Luck
Andy
p.s I only have 9 connectors and if you want a couple you have to be in the U.K because i get free stamps from work
