i'm trying to buy my first 4x5 on a budget. after reading/looking, i've narrowed down to getting a used sinar. there're several available on the auction site, but i can't decide between the f1 and the p.

i'll be using the monorail in a studio setting, so weight and portability is not an issue. ease of use (i'm a total newbie) and performance are.

from what i gather, the sinar p (almost twice the price?) is a better camera compared to the sinar f1, but in what ways? can i get an f1 and replace with parts (standards) for the sinar p later on?

any advice and recommendations for either of these cameras is greatly appreciated.

thanks.
