I need a cab manager (not $100 one)

[orangekid]

I searched far and wide thru google, ppcgeeks, etc.. and I can't find a freeware cab manager. I can't afford $100 for wince cab manager, and in order to get my custom ROM tweaked I need to edit some cabs. Any idea where I can get a freeware cab manager or a "lite" wince or something I can use to add and remove files from some cabs? would really appreciate it!
