I bought one roll of the new E100 on Friday, managed to shoot it over the weekend with proven ME Super body and tomorrow after work I shall see the results
I didn't preorder anything, the couple film shops around here didn't have it registered in eshop at all. I checked it semi randomly and it was there on stock last week. It's a small shop, I visited shortly before closing time but one other customer came for another two rolls and now they show over 50 in stock, maybe because it's not much advertised. Cost with tax is 13 EUR which is considerably cheaper than Macodirect at 15 EUR which is out of stock anyway.
Due to high price I bought only one, there's still cheaper Provia, although the relabeled older Provia known as Agfa Precisa CT-100 is no more and I have only one more roll of it. For slides I prefer 120 anyway and still have some Provias left. However it seems Ektachrome will be the only one left soon, so it comes at the perfect time. Never shot Kodak's E-6 before, as my more serious interest in film came after it had been discontinued already, so I'm excited to see if it wins me over.
