For 20 years I built furniture (regularly, but still a hobby) with an early 70s vintage sheet metal Craftsman contractor saw which I acquired well used. A few years ago I found a deal on a Delta Unisaw. It's an awesome unit, infinitely better in every respect than the saw it replaced, but the quality of my work did not change as a result of the new saw.
I'll tell you what though, it's an absolute pleasure to use and it makes me a lot happier than the Craftsman did.
My serious advice would be to get the best saw you can handle (but that's my advice with any tool, lol).
So, realistically I'll never (well, in the not for several years) be able to buy more than the Delta 36-725, and I'll need to wait for it to go on sale to do it.
I need something that can be moved to the outside to actually use it (knocking out the idea of getting a used hybrid or cabinet saw).
I was going to get the Dewalt 7491RS with the current sale Lowe's has plus a 10% off coupon I have.
Would it make sense to try to wait for a sale on the Delta, or is it not going to make the quality of my work that much better? I read a lot about inaccuracies in the construction of the portable saws that make them less precise, but not sure how much it matters.
EDIT: Looks like the 36-725 is discontinued. None of the stores in my area have it anymore, and I found a used one local missing a fence and Delta says the fence assembly is no longer available. Is it worth my waiting to see if a replacement will come, or in this price range am I just as well off with that Dewalt?
