I may be biased, but...
If you want a drill press that was designed with woodworking in mind, I'd suggest you look for a used Shopsmith. Besides being a Shopsmith nut, here are some logical reasons.
1) infinitely variable speed from about 800-5200 rpms.
2) designed with woodworking in mind. Every time I see an article in a woodworking magazine about making a jig for your drill press for some woodworking procedure, I think, "gee, my Shopsmith already does that" Has locking miter & alignment fence on table & table pivots
3) mortising accessories available
4) can do shaping operations
5) even better at horizontal boring...I think I use it horizontally more than vertically
6) you get a great 12" disk sander that allows you to move the disk to the work instead of moving the work into the disk (think horizontal drilling with a disk on it) Way more precise than moving the wood into the disk
7) you get a lathe as a bonus
8) they're on casters for mobility
9) Good used machines can be found for around $250-450
There's more stuff but I figure, since I'm a "Smith" guy, you'd only want some of the basics, also this kind of thing always seems to start one of those "Shopsmith vs separate tool" discussions, and that's not my point. I'm not saying to get rid of your separate tools, I'm saying that the Smith is a great woodworking drill press that can be had used at a reasonable price & has a bunch of "bonuses".
