Most trackers will let you slow the sample down without retriggering the sample, so they are ideal for this technique. And it will sound like a record too, not a tapestop, which is a completely different sound.
True, a tracker is a nice environment for manipulating a sample this way. Renoise, as recommended by Moses, is indeed
very nice. Having registered it somewhere in the beginning of 2005, I have been very pleased with it.
Anyway, I feel the different kinds of stops you can make with tracker-style sample speed adjustments aren't a
completely different sound from a tapestop, it's just a matter of creating different pitch/volume curves for essentially the same effect.
The Tapestop VST effect also lets you adjust the duration of the stop -- but yeah, you naturally have far more control when programming the speed/volume by hand. Of course, you have to work on an already rendered sample, so you can't apply this technique to your whole mix on the fly, like you can do with a dedicated insert effect.
There are many neato tricks one can achieve with trackers, so Jonesee, if you're interested in tweaking material of the Aphex Twin kind, you definitely might want to check them out at some point.
And oh, the modularity of the free Buzz tracker VexaDJ recommended is also great. There have been some amazing tracker/modular/mad scientist constructions coming out of that community during the years
