I'm also a solo practitioner SE and architect. I purchased Revit LT for doing projects on my own as an architect. For that purpose, Revit LT is hard to beat given its price compared to full Revit (about $1200 plus $200 annual maintenance for LT vs. $5800 plus $1000 annual maintenance for full Revit). There are some aggravating limitations of Revit LT, mainly (1) there's no in-place component modeling, as there is in full Revit, and (2) there is very little ability to collaborate with anyone else with LT. On my projects where I'm acting as a SE, I can load the architect's Revit model into the background, but there's no real ability to control the visibility of the background model's components, families, lineweights, etc. This means the architect's background model is either on or off - you can't "freeze" layers or turn off furniture or manipulate the imported file in any way (except apply a 50% grayscale to it uniformly). This is a major limitation of Revit LT, although to Autodesk's defense (I can't believe I would ever say that), LT is not intended as a collaborative tool - it's really for solo practitioners who don't need to bring other consultants'/designers' models in, or at least do any sort of collaboration.
My SE projects are fairly small, and I'm using Revit LT basically as a drafting tool for adding structural linework and annotation. That's not really what Revit is for, but it works for me. Drafting in Revit (or Revit LT) is a bit clunky compared to traditional CAD, and less efficient. But again, that's not where the power of BIM really is. Since I can't really model anything collaboratively with the architect's model, that's really all I can do. For other architectural design and documentation, I'm 100% BIM on modeling and documentation, and using Revit LT as it was designed.
I'm fairly happy with Revit LT, given what it cost me. Is full Revit worth it, as a solo practitioner? That's a bit questionable. Actually it looks like Autodesk is pinching users and now selling only a package called "Building Design Suite," which includes all the different flavors of Revit and AutoCAD together, regardless of whether you need all that, or want it, for a flat $6800 fee. Previously, you could buy Revit Architecture, or Revit Structure, or Revit MEP, depending on what your profession was (makes sense!). Now you can only buy one giant package (at least from a quick glance at Autodesk's Store, that's what it looks like). I wish I could switch to ArchiCAD, butI have too much experience with Revit already, and I'm not really willing to have to spend the time to relearn BIM on a different platform, as long as LT exists.
structuralengr89, I would be interested in hearing what kind of structural analysis packages you're using, if any. I've used different packages through the years, but I'm a bit more picky when it comes to shelling out cash for software that's of limited use to me as a solo SE.
