I've built quite of few with sony p32s and p41s but haven't in a few years. I started a couple more this past winter with parts I had laying around but ran out of time, hope to finish by deer season. Some of my cameras have been in use for around 8 years without many problems. I would recommend going to Hag's House, www.hagshouse.com, build your own homemade trail camera or video game cameras for your research.
