I know a lot of people might disagree with me, but I'd say no to both, but each of them for a different reason.
Sega CD: They are notoriously unreliable consoles, especially the model 1, and the games are very hard to find. You'll likely be going to Ebay to get most of the good games, but it'll cost you.
32X: It has a very small and mostly unimpressive library of games. Many of the games have better ports on other consoles.
Bottom line, if you can wrangle these consoles and the games for them for cheap go for it, but unless you really have a thing for either I'd pass.
