I have started a new service,
Bitcoil. If you have an Israel bank account, I will buy and sell bitcoins for Israeli New Shekels. Payment is done by bank transfers.
For now, orders are processed manually and placed by sending me an email.
Taking into account the fees involved in exchanging ILS and USD, required for most other methods of buying and selling bitcoins, I believe my service is the cheapest way for Israelis to exchange bitcoins for amounts of >100 ILS. Please let me know if you think I'm wrong.
Questions and comments, and of course using the service, are all welcome.
