OK, here is mine, showing some mods useful to any saw:
Extended table, re-saw fence, bin for tools, hanger for miter, bright light etc. I have a slip on outfeed using a hinge and prop. As the fence hits the guides, I keep a spacer board for ripping thinner stock so I don't have to touch the fence. Yes, there are times I wish I had a 20 inch saw and had to resort to my table saw. Someday I'll get a track saw. As far as height, I can't see the need for over 10 inches. When I mill rough logs, I either adz them closer or the good old WEN handheld plane to get a flat enough first side and knock off high points.
Guides seem to be a personal choice. I prefer a rear guide that runs on the outside of the bearing, others like it running on the face edge. Some like disk guides, cool blocks, Applewood, or ceramic. I find bearings to be fine. How they are adjusted matters more and for re-saw, in a perfect world, you would not be touching the side guides. Actually, I use a spinning guide as a hint I am drifting. I have considered if for re-saw, side guides that actually touched, like graphite or apple, might be better. Maybe I'll make some and see. I could cut a wood disk with an eccentric hole to just replace the side bearings.
The old C-frame Delta and clones are exactly what I would never want. A lot of great work has come off of them. The band does the cutting, the tool just turns the band.
As far as Delta quality, once upon a time they were excellent. I made a mistake of buying an older Delta drill press made in Taiwan assuming it was old enough. Nope. I don't know what year and tool to tool they went to crap but Delta is not necessarily Delta. Any tool that is a branded OEM, quality is what the brand pays for so it can vary. If OEM branded, you may have a little more confidence. If it means anything Harvey is an OEM. Griz and Jet are just paper companies. Who makes any given tool may change year to year. A good example is the old Emerson design 6 inch planer. It is on at least it's third OEM. Mine, branded Ridgid, was built by Emerson. Most Craftsman were. They are now made in the Mainland. Probably 90% of all traditional drill presses used the same head castings.
