Say he charges an average of £5 a pop, then it might add up to buy your own if you have several to fit/refit in the near future, but after that it's a tool that you will likely use less than, say, Allen keys or spanners.
How would you remove the headsets? If you already have suitable tools then it makes sense to be able to do the whole operation; if you're just bashing them out with an old screwdriver then a proper press makes less sense.
If your LBS is convenient and always likely to be able to do the job when you need it done, then I would be inclined to stick with him: it's often difficult to justify, on the grounds of loyalty etc., paying over the odds for parts you can get on-line for considerably less, workshop time is the one aspect that your LBS will always beat Wiggle et al and from which he can make a living.
Workshop jobs are often the areas that benefit from experience and Wiggle won't bail you out when you absolutely can't free X, or Y won't fit Z.
