At US-dollar pricing, the cost is rather good for just the legset.
The 055XPROB is an extremely solid and durable set of legs,
and is often suggested as a starting point for someone looking for
a 'serious' tripod without entering financial meltdown.
Figure that you got a bonus head thrown into the deal.
Play around with the head operation, and figure out if it suits your
purposes. If it's not as simple or quick to adjust as you prefer, then
you'd do well to consider an eventual replacement.

Quality and cost in the area of tripod heads is all over the known fiscal
spectrum, but it's worth noting that one person's particular preferences
and needs are not what is necessary for each and every other person
to achieve their own desired results.
I've been very happy with what many will consider 'budget' heads, while there
are other heads on the market that cost less than mine, which are even considered
to be a step or three up in quality and features over what I own.
Take it all with a grain of salt:
Read the stickies, do some research, and check them out in person whenever possible.
Compare whenever possible, but ultimately, decide for yourself.
