You could also get a Maglite drop-in along with a smaller 1 or 2 AA light. Keep all of your lights up to date. Also, can you get packages? It might be easier (but maybe slower) to buy a light not available locally and wait for it to ship to you.
I recently got a Zebralight
SC51c and I like it alot. It's a warm white LED and provides great color rendering along with many modes. High mode is really bright while low mode is great for getting around the house at night. There's also a brighter Cool white version (
SC51) and a warm/neutral white version (
SC51w) if you want different tints.
The Fenix lights are great too,
Fenix Store is a great place to get them in the US, but I'm not sure about Greece. There are stores that stock Fenix lights in Europe, but I don't know which ones.
Also check out the
4sevens Quark lights. From what I hear, they are nice and also come in neutral white if you don't like the cool white LED tint. The Quarks Minis make great keychain lights too.
