I just picked up some Meguiars Ultimate leather Balm from Walmart the other day after reading about it on some detailing forums. Meguiars claims that it is it's highest quality leather conditioner with the highest concentration of premium ingredients. I tried it out yesterday on my drivers seat and really like the stuff, it leaves a nice, not to shiny finish and the seats feel softer then when I started. When I do the passenger and back seats today I'll try to snap a 50/50 pic to upload. Other products that I've used and liked are megs Matte interior protectant, 303 protectant and Optimum Leather protectant plus. Those all have varying levels of cleaner in them. For deeper cleaning I just use Megs APC 10:1 with a micro fiber and then follow up with conditioner/protectant.
