If the price of the Miller is unbelievable to you and the Manfrotto even looks pretty high, you might want to consider the Velbon:http://www.bhphotovideo.com/c/product/4261...id_Panhead.html
I have one and think it's pretty good. It's a tad hard to get the adjustment just right, but when you do it can be pretty smooth. I find it usable, if I do my part. It isn't the best fluid head out there, but it probably is the best for $150.
