You should also sound out your local hardware stores for power tools, they all vary, for instance I was looking for an electrical nailer, just a small one capable of piercing hardboard and softwood battons, as the one we brought from UK had given up the ghost after only 1/2 an hours use. We tried a number of outlets, including Profi, and the cheapest/most powerfull/for the money, was just outside Roda. And it is still in regular use.
But since then, the same shop has'nt had what I want, or if they have it has been expensive compared with elswhere.
In a nut shell, it pays to do the rounds, item by item.
Insidentally, it is impossible to compare prices with UK prices for power tools, the cheap as chips models available in the sheds, (Homebase-B&Q- Focus- Wicks-what have you) are manufactured to a price, and do not compare to the quality on sale in Corfu. For instance the Black and Decker range on sale in Profi is "The Professional Range" only available to the trade in the UK. And they are about the same price as UK prices.
It depends on what you expect from a tool, if you are likely to want to reduce a bedrock stone in size, or perhaps create a hole in the 32" thick wall to cater for a new window,even with modest inroads, you will need a profeshional tool, not a "Shed Special at 1/8th of the price" On the other hand, if you are antisipating drilling a number of screw holes in your old stone walls, a cheapo will do.
As somebody said earlier, when it breaks, throw it away.
And I have been ferrying tools out to Corfu for years, but now I find the local equivalent comparable, like for like.
