Chris, many manufacturers make high-quality sliding compound miter/bevel saws. Radial arm saws are nice, and I've used them for many years; but for my needs the Makita 10" sliding compound miter saw fits my needs perfectly. Often you must look at what kind of work you're going to need a particular tool for. I've never met an easily portable radial arm saw - if there is even one available.
In reading your thread starter, I am curious how you're making dado cuts on your band saw - are we talking about on really short boards?
You will not find many people using their table saws for resawing work for a number of reasons, but personally I would prefer a table saw over a band saw for my kind of work - but I have both. I am getting older and my hands are not as steady as they have been in past years, but for me; super-straight rip cuts and cross cuts are best achieved with the table saw.
Chris, all of these tools have their place in the woodshop, but I really enjoy my sliding compound miter saw and would feel very handicapped without it. Also, I have several "docking locations" for my SCMS and this enables me to move it around easily!
