hi,
after 15 years using the berlebach levelling head i want to buy a 3 way head.
i would love to buy a geard head like the manfrotto 400 but its to expensive for me.
alternatives are,

1. manfrotto 229
2. gitzo 1570
3. manfrotto 160

i will use it with a heavy field camera and long tele lenses.
can somebody compare between them? what would you buy.
thanks, boris
