I've used a 94 spider and TA rings to get that sort of setup before and would recommend that over the other options.
The rings you've linked have a weird mounting system to get the 30t to fit. 33t is the smallest ring you can fit on a 5 arm 110 bcd pattern with regular chainring bolts. Had a look around and they have "solved" this by tapping smaller screws into the 30t ring directly.
