I found the Agfa Vista 100 and 200 were quite good when printed by a decent technician. 400 and especially the 800 I was not so keen on.

About 4-5 years ago was the best time for film on eBay. I regularly found bulk tins for $15-20 and 120 films for $1 or less as pros emptied their freezers as they went digital (one of my best scores was 90 rolls of 120 Plus-X for $85). I am blown away by the prices these days. There's an old expired roll of Fortepan or Fomapan from the 60's that someone wants $10 for! PLUS shipping!!
