Reversal film for me is like a guilty pleasure, like chocolate, and I'll gladly put some money towards it...
I really like Fuji's film and this is what I know and use the most, but have been growing increasingly nervous about FujiFilm the company...prices do nothing but go up and emulsions keep being cut from the roster. I admit I never used 100/1000 or Astia - but it was nice knowing they were there. Provia 400X and it's predecessor were great, and I still have a few rolls to use...but it'll gone soon. Velvia 100F was a nice blend of fine grain without going quite too far on the saturation for me, I think i have 5 rolls left of 35mm and have used up more of the 120 than I anticipated this summer/fall. Kodak offers nothing to me anymore...Rollei/Maco is the only other option that I've tried recently...still undecided.
So, to hear that there's a group of people out there that share my love and passion for chocolate...er...slide film, and that in exchange for some some cash to work with they'll give me a taste...er...roll...and they plan to keep working to make even more/better/diverse goodies in the future...sign me up!
I also think it's awesome that one of the incentives is a post card that they've all signed.
