Sites for instrument samples

I'm looking for packs of instrument samples that I can use with a tracker like OpenMPT. Any sites you could recommend? I'd prefer sites that don't require registration, or at least ones that don't require any personal info. I haven't set up uTorrent yet so I don't feel like futzing with torrents.

doesn't really fit your request but proaudiotorrents.org is the greatest site fr samples, plugins, apps, everything pro audio related.
