LOL You're in luck cause you can get ripped off for 20$ today !  :lol:

a600 is not such a rare stuff, he can get a full unit for 20$ ! (maybe even less, from UK)

Of course it would be a problem. In my experience avoid all NTSC amigas which are not AGA. Most amiga software is made for PAL machines and they give all kinds of strange trouble on NTSC machines (This coming from a user in Japan, NTSC land).

There is no AGA A600. It is ECS.

If it's coming from canada it's probably NTSC. But ask the seller, he might have imported from Europe. If it's NTSC I say don't buy it. NTSC A600 are kind of rare also, so it might cost a fortune.

Your A520 is a PAL unit, you can't use it with a NTSC unit (well maybe you can use but I'm sure either the color or sync rate will be broken)
