Ive got the Bogen 503HDV and 525 Sticks, to many members of the site, they are "entry level" but B&H lists them for $912.95, price wise, thats not low in my opinion, but who knows?
I recently purchased a 503HDV Pro fluid manfrotto head. I would consider this to be a "entry level" tripod head. The pans/tilts are fairly smooth on wide shots but you will notice camera shake while starting & stopping your pans/tilts while doing fully zoomed shots. Still a step up from a 702 or 128RC head.
From what I've heard, from a price and quality standpoint the Libec LS-38 is very nice, for $650. Once I recoup from my latest purchases it's next on my list... Somewhere on here there is a thread with a link to a review of this tripod setup, and they didn't really have anything bad to say about it.
