Flashhole, you live in an area fo the country that is rife with old woodworking and metalshop tools. As a woodworker, I have for years admired those that live along the eastern seaboard where antique sales, estate sales, and other sale events displayed such a large quantity of tools from yesterday. And yes, for the most part, the mechanics of them are
much better than those of today.
Now, I happen to have an old Delta floor-standing press that my wife found at a glass shop that was going out of business. It was rusty and used, and only cost us $75. It was made in about 1938. At that time, Delta was building their tools and working out of a two-car garage in Milwaukee. They didn;t cast everything there, rather some things were cast for them, but they had an assembly and machine shop there. I learned this from Delta almost 20 years ago after purchasing this old press and calling them for parts, a manual, and paint. The lady I spoke to gave me a history "lesson" on Delta-Milwaukee and I think she even sent along copies of some aged (histoical) writings about them when she sent my manual and parts.
As MontyF said, the quill lock is a desireable feature and one that mine has. The newer models, or few of them, have a "functional" quill lock, IF they have one at all. I find it indespensable and will NOT, for any reason, buy another drill press that doesn;t have one. My old Delta has everything I desire in a press: accuracy, weight and stability, speed adjustment (double graduated pulleys), a 1/2" chuck, and...... a quill lock with depth stops.
As far as wobble is concerned (accuracy), I'm not aware of any one brand that has less runout or wobble than another. Being an American, and knowing what I know about woodworking tools, I do stay away from the made in China tools, opting instead, whenever I can, to buy older American (or Canadian) tools. Now, some these China knock-offs are quite good, according to tests done by respected woodworking magazines. And....sadly, American made tools are almost all made foreign anyway these days (except for the old stuff

)
If you would like to see a picture of mine (in case you're interested in looking around for older equipment and would like to "see" what to look for), give me your email and I'll send some. The good old stuff is out there, and in my opinion, it's well worth a few weeks or months investigation to find them and see if one or more is what you're after.
Good luck!
