No scart in NZ anymore, unless you can find an old Euro branded CRT. There are scart to rca/component about though.
Isssue with old CRTs are that they are on their last legs and I've had a couple die. Good thing they're cheap.
Scart does produce a nice picture, a little better than scart is Amigamaniacs rgb to svideo adapter. Kipper2 makes a similar version of this which he sells through Amibay or his website.
Both options a lot cheaper than $300....the adapter cost me $20. However after using an Indi both on the 500 and 1200 I wouldn't bother with the other options. The picture of the Indi is amazing.
