Well, you guys got this noob/lurker to come crawling out into the light!
I've been building furniture for about 20 years, and only recently got the yen to build guitars, so I have a pretty healthy set of hand tools including planes and spoke shaves. My best planes are the ones from Veritas (a low-angle block, a skew block, and a medium shoulder) Lie-Nielsen (a bevel-up jack) and the one's I built myself as suggested by Jim Hepler. Wood planes are really easy to make, and if you can get some Lignum Vitae to laminate on the bottom as a sole, they're outstanding. David Finck's book really tells you all you need to know about the process.
That said, I have some vintage garage-sale Stanley's that aren't good for highly figured woods, but once tuned up have been great tools.
One thing I haven't seen mentioned is scraper planes. They're hard to find, but are great for working figured woods and I would think should be a valuable addition to any luthier's arsenal. I don't think that he's making them any more, but a fellow named Paul Hamler used to make these super solid cast-brass inserts that would convert a wide-blade Stanley or equivalent to a scraper plane. I don't think he's making them any more, but I was fortunate enough to grab one when he ran a batch, and have two vintage bodies - a 4 1/2 and a 7 1/2 Stanley - that I've dedicated to use with this insert. If interested, wouldn't hurt to contact Paul to see if he has plans to run another batch of these anytime soon -

In the pic below I'm using my Veritas low-angle block with a high-angle blade and the optional knob & handle that makes it the equivalent of a #3 smoother, and the Stanley 4 1/2 with the Hamler scraper insert to work the joint on some quarter-sawn white oak for a coffee table. To get the figure to match right the grain had to run in opposite directions on either side of the joint, hence the high probability of getting tear-out. These two planes made the job do-able.
