Brian,
I have a suggestion for you if USA old-iron is something you might consider. Look for a Rockwell Model 15-017 (or variations on the old series 15-000 head.) This was a 15" industrial quality drill press made by Rockwell beginning in the early 1960s. They made 100s of thousands of them in several configurations and they were priced reasonably enough for home users and were strong and accurate enough for industrial use so they were used everywhere. Every decent bowling alley in the country had a Rockwell 15-017 ball drilling rig. These days they sell for between $50 and $450, depending upon your luck. I have seen $50 ones in like new condition and crapped out $450 ones. Between online Toolparts stores, eBay, Craigslist, and a couple of machine tool companies who bought up Rockwell spares, even the cast iron parts can be had. I have had a 15-017 bench model for 40 years and it still runs like a new machine.
As an aside (no gloat intended) I recently found a crudded-up floor model 15-017 for $125 and after scraping off the crud I found an almost like new machine with an almost untouched table. It was like new mostly because it was built so well to begin with. The column was in pretty bad shape but I found an NOS column, added a few other small NOS parts, and a new Jacobs 0-1/2" chuck, and I will end up with an essentially new industrial machine for less than $300. As an extra added bonus I discovered this machine was built as the Slo-Speed model which has a larger than standard spindle pulley and a lower spindle speed range - handy for things like reaming and honing. That NOS Slo-Speed pulley alone brings $65-$95 on ebay.
The downside of most old drill presses is that sometimes the tables are drilled up pretty badly but in a worst case this can be remedied by simply screwing a sheet of steel to the table face. The other thing that goes sooner or later in the Rockwell 15's is the spindle return spring. These are just blue clock spring steel, but they have a crook and hem fold on the loose end which must fit a slot in the die cast return spring housing. This makes for a very difficult for home repair and while NOS spring housings are available NOS springs are not so return springs are invariably used and scarce. Aside from these points these are great old machines.
