I am approaching my first year making knives and have a little advice FWIW.
I started with a Craftsman press I refurbished and it has served me fairly well. See below.
About 2 months ago I was able to get a HF mini-mill and the run-out on it is better than my craftsman DP.
I was able to get this on CL for 120 bucks with a decent vise and a few odds and ends for tooling.
It does have some upgrade features such as a belt drive system, etc. I haven't done these yet.
Since I got the mini-mill I've used my DP exactly once, and that because I had to drill something too long to fit under the mill.
The older 103.xxxxx craftsman benchtop presses are exactly like the floor models, except for the shorter column and slightly smaller base.
I wouldn't hesitate to get one of these in a bench model instead of the floor model if the quality was the only concern.
The one nice thing about the floor model is it doesn't take up bench space. That to me would be the only major concern on one vs. the other, unless you were drilling something really taaaalllll.
I put all new quality bearings (4) in my Craftsman and it's great. There are some accessories you can hunt down on CL that make it nicer. Slow speed pulley and table lift crank are the main ones. You should be able to pick one of these presses up for 100 bucks or less. It's some work to rebuild but there is a ton of info on how to do that.
If you get the drill press, which will easily get you started, you'll probably eventually start looking into a mill of some sort. I'm in the middle of that process. The HF mini-mill is nice for drilling, and will do some machining, but a bigger mill would suit me better. I will keep my DP though.
No matter what you get, learn to check the run-out before you buy. This is one of the more critical items for knife making.
Craftsman before and after. The top one shows the middle slow speed pulley which I recommend. The bottom one shows the Vari-slo speed attachment with isn't great for metal:
