Unfortunately when it comes to heads there's a reason the good ones are so expensive. If you want smooth pans and tilts you'll need to spend the $ to get you there. Do some comparisons. Look for a refurbished fluid head and save up. In the mean time you can always rent. You can usually get a 100mm ball mount Sachtler or Oconnor head and sticks for around $35-$50/Day. Take a look at Libec, Cartioni, and Vinten as well.
