I think you have to look at your whole situation to make the decision. If it's cheaper to buy it on vacation (due to taxes/exchange rates) then it makes the most sense to do that. If price is essentially the same, it might make sense to buy at home so then if there is a problem it's easier to take back to the source you bought it from. Not that you can't take it back or have it repaired if you bought elsewhere, but it might be more of a hassle. I think you have to look at your past history, if you haven't really had to return things or have repairs it's likely not as big a concern, but if you have had bad luck then you might feel more comfortable buying from a location you can easily return to.
