I guess the reason Im leaning towards something faster is that my last 2 a1200 accelerator cards where a 50mhz blizzard mk4 and a bppc (25mhz '040/175mhz 603e), so I know I probably wont be content with anything below a 50mhz '030, and even then Id prefer something a little faster.
Me too, although the ACA boards are really well priced (especially that 030/28) I already own a 030/50, and as i'm a demo scene whore, I could really do with someone making a new card that's meatier.
