Just buy the OSSC!
In fairness make sure you have SCART/RGB cables for what ever you plug into the OSSC as it doesn't do display over composite (only sync I think).
With the PS2 I've switched a bit between RGB and SCART depending on what I'm playing, RGB looks great on some games but on GT4 the combination with the PS2's interlacing just breaks it a bit (same for burnout 3 with the high speed reflections).
As the aside/back up for the OSSC, it's been a blast getting every console set up with it, worked wonders with my Japanese N64, Cube and Saturn. There's enough in the box to make it really help get classic consoles working on my 40 inch tv they weren't designed for.
Thanks. They do offer a refund if you don't get on with it it seems.
This video sowed the seeds of doubt re 480i issues.
I'm looking at this RGB cable
