I know it must be frustrating for you, but you are new to the collecting bit, the purples are a delight, and look, I`ve never see one and then two come up in two days....
So who knows, there is stuff out there, you have to be patient and it will find you, usually when you least expect it and are not looking for it...
keep looking with enthuisiasm and you will find stuff!!! in the meantime enjoy whats about, keep asking questions and be open to the learning!!!
Cheers, Mike
