I’m working on a project with a 19x26" panel that I realized after gluing still has a bit of a twist in it across the three boards. In the past I’ve simply sanded down panels, but I think this one is going to require a plane. Thing is, I’m still fairly new to woodworking and don’t have any planes yet so I’ve been doing my homework on which to get.

I generally avoid buying junk tools, especially Chinese junk so that rules out a bunch of the options. Plus, I assume I’d find it difficult to tune up an old one since I’m not knowledgeable enough about them yet. Because of that I’ve ended up going straight to the top and considering either Lee Valley or Lie-Nielsen.

Given that my immediate task is to flatten a panel I was thinking either a #5 or #5-1/2 high angle jack plane knowing that I’d likely expand the collection in the future with a smoother as well, but for now I’m only looking for a first one.

Does that make sense for me? If so, any tips on deciding between the #5 and #5-1/2? The #5 is a bit cheaper, but it seems like the slightly bigger #5-1/2 would be good if I followed it up with a #4 in the future. Specifically I’ve been looking at:
