Freestyle advertises a single use B&W camera from Rollei called the "Rollei Retro 400 B&W Assignment Camera". I could not find it on their website, but it is on page 35 of their most recent catalog. Sounds like a cut above standard disposables, and it is 24 exposures. Might be interesting enough for one of the Round 6 cameras; it lists for $9.99.
The ad professes a "high quality lens". Has anyone tried this camera? It may be better than a $10 off ebay Canon cheapie. I'm headed to Freestyle this Saturday and I can check it out.
