What he said. Definitely try BIAB and 3 vessel before committing real money either way. Hook up with a buddy who has a 3 vessel system. You can do a small BIAB in a stockpot on the stove.
Also search for "no-chill" brewing. It was developed in Australia partly because it requires less water. That may be a consideration for you in Beer Sheva (good pun).
Any way you decide, do not worry that you may have made the wrong decision. All the processes work and can create prize winning product with the proper care. Brew on.
