Pixel has just announced ps2 packer .03b on our forums. This version is still in its early stages so please feel free to test and post your findings. So far the major changes have been the addition of more compression stubs, most noteably a lzo(which sjcrunch is based on) and a null stub for test purposes.
The author has also graciously allowed us to mirror the files here.
update pixel has updated his package to .03b2 with UCL compression stub giving much better compression results!
They all worked for me. I am running them from ps2link, ps2menu, and dms3's dev.olution mode. All of them are working for me, for any packer. I actually tested it on ps2link itself and ps2menu itself. Now, if you have troubles with other configurations and binaries, please report!
