Ajani's points notwithstanding, if you're willing to buy used, there are some great deals to be had. I also believe that Israel's import duties don't apply to used gear, although I don't know that for sure. I also believe that not all areas of Israel have the same import duties and so depending on where you live, you could reduce your expenses. You may also be able to ship to a PO box in a lower tax zone, although I don't know the specifics of the laws in Israel. I'm certainly not advocating that you break the law.

Regarding the 220v, you would probably be best ordering from European resellers. You may also need to invest in some good adapter plugs if they don't match what you're getting from Europe. Actually, if there is one item you would probably not want to buy from abroad, it's a good power source. Many countries have varying degrees of quality when it comes to power, so a power center designed specifically for your country or region is probably best.

Start with eBay. They have good resources for buyers, payment, and all the legal details that are involved. I have sold gear to people in Israel and shipped it from the US w/o too much trouble, so there should also be people near you who can assist you in getting started.

One more thing: aren't there hi-fi manufacturers based in Israel? Certainly your pricing on their gear would be better than it would be to anyone elsewhere.

Anyhow, I hope this helps.
