I have the Triton lunchbox thicknesser TPT125. I have used it to thickness mostly white oak boards and it has performed beyond expectations for a cheap machine. I take very thin passes - less than 1mm per time and have got a good consistent thickness from it which just needs a light final finish with a hand plan or sander.
You mention regularising and smoothing old boards, bear in mind a thicknesser will essentially follow the profile of the bottom of the board being thicknessed, so if your board has twist/wind in it to begin will it will still have the wind after passing it through the machine. You need to get one side flat before passing it through the thicknesser as this becomes the reference face. You can also build a sled and use wedges to provide a flat reference face, make a few passes then check the planed side is flat, flip it over and go from there - plenty of tutorials for this kind of thing on YouTube, search for Planer Sleds.
