Will you want to carry your tripod very far? Weight is a definite consideration, and for me buying a tripod is a surefire contender for "buy right and buy once". I can happily carry my lightweight tripod and head (1.3kg) all day long on the offchance of needing it, but my Redsnapper weighs twice that, and although it's excellent quality and very sturdy, it's too heavy to lug around all day.
