Just keep your eyes peeled on the members ebay finds thread (the one you posted in first) and they are likely to be posted by someone, if not those exact alloys, then there's all manner of different ones (most at reasonable prices as well) that are posted on there all the time. Or you could just search ebay for them yourself if you don't want to wait. Good luck, mate
On a side note, until recently I had those exact wheels and actually sold them right here on the MSC. They came off my 1.4 SE+
