Noise reduction for Mac music files?, Want to reduce surface noise on 78s. Options

I've had good success transferring cassette and vinyl recordings to iTunes using a freeware program called 'Coaster.'  But before burning CD's of my noisy 78 RPM recordings I'd like to find some program that features equalization and noise reduction.  I know about Spin Doctor, but that requires purchase of Toast and moreover it does not have 'real-time preview,' which permits you to listen while you adjust the settings.  There are 4 programs that I'm aware of with this feature, but I believe all are for Windows machines: Sound Laundry, DCART, Wave Repair, and CoolEdit (just recently added the preview feature).  Does any one know of any comparable programs for the Macintosh?  (I'm not an audiophile--just looking for something relatively simple and inexpensive.)

I purchased Toast/Spin Doctor for this purpose which certainly does allow real-time preview. Basic procedure is to fire up Spin Doctor, transfer the record to your hard-drive (Spin Doctor will save this as an AIFF file), and apply filtering using Spin Doctors 'slider' controls. One can apply noise reduction, pop reduction, high end, low end boosting, stereo enhancement, and volume adjustment. When it sounds as good as you can get it, the last step is to save the file to permanently keep the settings. This is not a miracle program, however, but I am satisfied with its results and is is pretty easy to use. I would say that you can eliminate about 50% of unwanted noise before you start seriously cutting into the fidelity of the original recording. There is another program called Ray Gun from Arboretum Software which I believe achieves similar results and can also be run real-time either as a standalone program or as a VST plugin.

p.s. not sure but I think the Windows version of Spin Doctor doesn't allow real-time tweaking.
