Opinions on Dr. Tim's One&Only

[Fisherlander]

I am considering cycling my new 29 Gallon with Dr. Tim's One&Only. My LFS is recommending it (I'm not sure how much that means). The reviews of this particular product seem to be pretty good, but people seem to have a bad opinion on "bacteria-in-a-bottle" type products.
Just to be safe, if I am to get this product, I would still use 100% ammonia as the source as opposed to a fish. Any opinions?

I am a supporter of Dr Tim's product. His product s and previous bacteria bottles work as well. All other products are junk.
