HardwareGrowler isn't yet available separately. The current release is 1.2.2, included with Growl 1.2.2 and earlier; Growl 1.2.2 is available from the Downloads page:
HardwareGrowler 1.3 is in beta.
HardwareGrowler 1.2.2 works fine with Growl 1.3. You only need to download Growl 1.2.2 to get HardwareGrowler 1.2.2; after you copy HwG off that disk image, you can throw the disk image away without touching Growl 1.2.2.
That has not been my experience. Under Lion, Hardware Growler crashes not long after each login (and I have many crash logs to prove it).

That's good to hear. Any time frame for release or is there some place I can grab it?
Thanks again.
