Actually, the DX coding is easy to get around. There's resources on the web that show what the DX looks like for the iso you want, either scrape off the black coating to expose the silver metallic surface or use electricians tape to cover the silver area needed. Have done it many times, usually pushing 400 film to 1600 iso, takes about 30 secs. Something interesting the P3n can do that my MX or ME Supers can't do is run 3200 iso. Yes, the specs say the P3n is limited to 1600, but just ran a roll of Delta 3200 through mine thinking it would run at 1600, but surprisingly it metered at 3200 iso. Checked it against my K-1, developed the roll for 3200, it came out great.
The P3n/P30 is a tough durable,very underrated camera with some really good features including DOF and Meter Lock. It has four operation modes - Program AE, Aperture-priority, Manual & Programed flash. The location of the remote release is in a better location - low behind the lens and you can use the Cable Switch A, which I find easier to use than a cable release. Also, you can use lens without aperture rings, unfortunately you just can't control the settings directly like a PZ1p or a DSLR, but you can do it.
Don't overlook the P3n/P30, especially at prices you can get them for, they've great for a beginner and for a advanced user
