I was just looking to see if Amazon (US) has the 25/1.4 listed. They don't yet, but I noticed there were 4+ used 20/1.7 listed, with a couple starting below $300. They also show "in stock" on new ones at $340. I know some postings here have been "where are all the 20/1.7s?" so I thought I'd drop the pointer. Sorry Amin if this isn't the right forum for this. Feel free to move or delete. Just trying to help.
