I had a bad experience with horseloverz (almost to the point of having an accident with their equipment). And lots of fun to get a return back. So I won't deal with them again.
Horse.com and chicks are just that - cheap, low quality (I do buy grooming stuff from them though as I don't really care for the quality of my hoof picks and alike, NOT tack though).
I like Dover (we have it local), SmartPack, AdamsHorseSupply, and VictoryCanter. I did shop in ValleyVet too (very nice service), and JeffersEquine.
