I don't think there's any other software that supports the Saleae hardware. Their software is very nice at what it does, it's just missing a lot of stuff. Maybe because the hardware can't do it.
I recently finished up a lengthy review of the new Saleae logic analyzer (10 pages), but it won't be posted until early January, after I have a chance to talk Saleae directly. I specifically tested the Logic Pro 8, but the other models only differ by number of channels, sample rate, and price. Briefly, it's great for basic stuff, and the software is very well polished. But it's missing some important features for more complex work, like an external clock input, state mode, and any kind of meaningful triggering or searching capability. The analog inputs have such low bandwidth as to be of questionable value. The advertised 500 MHz sampling is only for three channels - if you use all 8 channels it's 100 MHz. Then you need to do 4x oversampling, so you can only work with systems running at speeds up to 25 MHz. Most hobbyists probably would have been just as happy with the (discontinued) original Logic at $149, as with this thing at $399. If you need more than the basics, the LA1034 LogicPort that trag mentioned looks very appealing at $389, true 500 MHz sampling with all 34 channels in use. The software isn't as pretty as Saleae's, but from what I can see it's very capable.
