I use Newzbin.com myself, have Newsleecher setup to auto load the NZB on download, it even repairs and extracts the files.
Can definitely recommend it.
binsearch.info = a free nzb generator... tick box of what you want, hit "create nzb" voila.
grabit is set up on my system to do exactly the same.
Load up binsearch, find item... create nzb, download, verify, extract, repair... 1 click.
