I use ken for all my shipping supplies except 60 hour heat packs including breather bags, dip and pours, nets, etc. I also buy alot of my filter media and oodles of food from his site. Its great to have so many shipping options and he still has about hte cheapest prices on the xp series of filters. He also offers his own versions of the filter cartridges that are very inexpensive. I like that he has a wide range of homemade foods with the ingredients available and the protein content, etc broken down in the description. He is just a guy with a business. I have had great experience buying from him and the shipping has always been very fast.
I am sure he won't mind not having your business newb, but he is wonderful to deal with and I will keep supporting his site and recommending it to other. His site has grown alot in the last 6 months or so.
