Other than the aforementioned Carbon HUD which is their branded version of Hold'em Indicator (which is still around, it's just not any cheaper to buy outright than PT/HM), not really.
You'd be better off with a trial of PT/HM and then just plan to buy it even if it's the cheaper small stakes edition. A tracker/HUD can more than pay for itself in the first month, if you learn it and apply it properly. Even at small stakes. So with a properly applied trial period, you could easily earn more than enough extra to pay for it when the trial expires.
Pretty much unusable for all but the most diehard software geeks who can keep it running. And I'm a career software geek, and I don't bother. You're far better served by PokerTracker or Hold'em Manager unless you care to spend more time patching code than playing poker.
