Totally. Once any sort of workshop budget gets to a certain point, having a set of reference squares, straightedges, etc. is a must. I've just gotten good at setting up our [Invalid or Expired Link Removed] including regrinding the blades to within a tiny fraction of a gram as a set. I wish I could take that thing with me when I graduate. It's coarse and needs surface finishing, but it really chunks away what you don't want. A recent addition was a Invalid Link Removed thicknesser which is a much more lightweight animal. Takes up to 2mm comfortably (the Robland takes 7mm!) and leaves a glossy snipe and knife mark free finish at the slowest feed speed. Definitely a finishing tool, but a little light-duty perhaps. We'll see.
The two large bed jointers we have are somewhat different animals each. The one I prefer in terms of flatness is an old old Italian (modern Italian machines are junk) thing which is totally manual, but really has the weight and solidity behind it. The other has a digital readout which I just can't trust. Nice when everything is sharp and cleaned up, but soon needs tuning back up....
Sorry, this seems to have drifted into workshop geekery. I'd think that these would be a good basis for a tool review, but I genuinely doubt that many people in the amateur or enthusiast class would invest in anything like these machines! Maybe a Hammer A3 if you're really having a midlife crisis on a reasonable budget....
