Yeah, i got mine off ebay too...£20. Only trouble is you`ll have to modify them a bit because the new ones have only two slots instead of three......you`ll see what i mean when you get them. Some people say cut another slot with a knife but i found that difficult because the plastic is quite thick....(plus i didnt wanna risk puting the knife through the lense)...i just got an old knitting needle and kept heating it up at the hob to burn the third slot that is needed.
