If you're looking for something semi-professional, I agree with Biggles that as far as Yamaha keyboards you should look beyond the PSR-E models and consider the PSR-S670 or higher. Apparently the "E" in PSR-E stands for either "educational" (because the PSR-E models include the Y.E.S. or "Yamaha Education Suite" feature) or "entry-level," whereas the "S" in PSR-S stands for "stage" or "studio." The PSR-E463 and PSR-EW410-- more so the PSR-EW410-- are the most sophisticated of the PSR-E models, so they're the closest ones to being semi-professional. Likewise, the PSR-S670 is the least sophisticated of the PSR-S models. So you might expect the PSR-E463 and the PSR-S670 to be somewhat similar in features and quality. But in terms of sounds, features, and capabilities, the PSR-S670 is much superior to the PSR-E463.
Regardless of which particular brands or models you're considering, I recommend going to the manufacturers' websites and downloading all documentation (owner's manuals, reference manuals, MIDI references, and other data lists) related to the models you're interested in, so you can read up on their specifications and see how their features work. You should also watch any videos and listen to any audio recordings to get a sense of whether or not you like the way they sound. And lastly, you should see if it's possible to try them out in a store so you can see how you feel about the way they feel, play, and sound in person.
