Reno is good stuff, albeit expensive. I've compared it to Venetian Shoe Cream and the Venetian can buff to a shine better than Reno which is nice if you are not putting a polish over the conditioner. Basically, I don't think you can go wrong with either as they are both interesting products.
It's expensive, yeah, but it seems silly to me to worry about paying $14 more (or whatever it adjusts to with volume considerations) on a year's supply of a care product for my several hundred dollar shoes =P. But yeah, it's not like you're going to fuck your shoes up without Reno.
