i also write in "unformatted". however i would advise not using ", p. 104" but "@104". the difference is, as far as endnote is concerned, the former is a suffix, while the latter is a page number. that means, if you ever need to change the output style of your page numbers (for example, from (blabla 2003, p. 62) to (blabla 2003:62)) you can do it with a couple of clicks if endnote already understands that it is a page number, but not if it is a suffix - then you will have to go through every citation individually to change it. also it is faster to type and will automatically do things like pp. instead of p. for multiple pages.
