Try out Cabos guys... http://www.versiontracker.com/dyn/moreinfo/macosx/25034

It's free, works great... I'm so happy I don't have to use Ares on the PC anymore! or pull my hair out with Soulseek... phew.

I've paid for and used Acquisition for some time. Worked great initially but went downhill after a year ago. I trashed it from my Mac when i downloaded an updated version and it refused to recognize my serial number. Forget about email support from the developer, he never answers your emails.
