Climax SP03B seatpost, any good? Alternative?

[StanK]

Or is there something else (good) in that price and weight range: sub $100 and sub 160g uncutted? Tried the search here and looked briefly some shops and ebay ... almost nothing, except this one.
Ah, yes, with 20mm seatback. 25mm is also fine - I guess.

Trying to replace mine (It has some clamping problems and look a bit worn out) although I am satisfied with the weight. But if I would change it for hopefully better clamping, 20-30g lighter would be a nice extra bonus
