If you're talking about Monarch Computers down in Georgia, i've used them before. Pretty average online vendor... nothing fancy, nothing to make them stick out as being either particularly great or particularly lousy... just professional and efficient. Last time i bought from them was back in the KT133 board era, when i bought an MSI K7T Pro2A from them. Got a good price on it, shipping costs were okay but not great, and i got it exactly 3 days later, and everything was in order. I'd feel perfectly fine ordering from them again.
