I'm currently in the process of dyeing my saddle black, it's not finished yet but so far I'm very happy with how it's going.
I took it completely apart, cleaned any particularly grungy spots, and used a 'deglazer' on the leather right before applying the dye (deglazer dries out the leather, so only put it on right before you're ready to dye) and I used Fiebing's alcohol based black dye. I did at least two coats, three coats on some areas. After buffing off any extra dye I applied Eco-Flo Super Shene to seal it (2 coats, buffing in between coats). All these products can be bought at Tandy Leather Factory - most cities have one, so you should be able to find them.
The deglazer is kind of nasty stuff - make sure you've got access to a well-ventilated area and wear gloves! The dye is pretty messy so don't wear your good clothes, lol. But it's a great feeling to look at the pieces that are done and know that I did that myself, I can't wait until it's all finished and reassembled. :)
