When searching for a SCART cable for my MiSTer, the bulk majority of options were VGA to BNC connectors, which wasn't suitable for me as I use a SCART switch and wated a SCART cable. Both retro access and RetroGamingCables have cable options, but they're frequently out of stock, and shipping for a single cable is quite costly at the moment.
Speaking to @evilsim, he suggested Tim Worthington's VGA2SCART 2.0 device which I've been using for a couple of hours with no issues. Picture and sound quality is fantastic and working fine on my Hydra 16-Port SCART Switch.
Setup was simple, put a jumper shunt on the Analog IO board to allow 5v power to Pin9 on VGA and then make sure "composite_sync" to is set to 0 (off) in mister.ini, as the VGA2SCART converts the H/V sync signals to CSYNC.
Hope this helps someone out, you can buy the adapter direct from @evilsim on eBay or pop him a PM here, I'm pretty sure he'll ship internationally.

"Useful for connecting an emulation computer to a television set or monitor. This device makes the VGA signal electrically compatible with SCART. The video timing must already be 15 khz, this adapter does not change the video timing.
Features:
Combines horizontal/vertical sync (of any polarity) with a XOR gate to make composite sync.
Accepts TTL composite sync through the VGA input.
Generates SCART status signals that put the TV into RGB mode when a valid sync signal is detected.
May be powered from via the VGA cable or via a separate DC barrel connector.
Aspect ratio selection (requires soldering a switch in place)
Blocks sync signals that are out of range (useful when connecting old arcade monitors).
Requires VGA and 3.5mm audio cables. If the VGA port supplies power (most do) it will use this, otherwese a 5V DR power source is required. A a USB power cable available to fit the DC barrel connector (O.D. 3.5mm, I.D. 1.3mm). The sync signal range blocker feature can be disabled by closing solder jumper J1."
