Have been using a bench top Craftsman 1/2 HP model for long time, but am limited by the lack of power. 7/8 spade bit is its upper limit before it stalls.
What do you have? What do you like? HP? I will look at floor models too.Thanks.

I got a nice old floor model Delta on Craigslist few years ago. Paid 125. A real steal. Super mint and I spruced it up and made some great fixtures. I would look for one of those or spend mucho bucks and buy a Jet or delta but the old ones are even better than those new ones.

I have a Rigid floor press that I bought at the home cheapot and absolutely love it. I use for drilling glass with a water feed and if there is one thing you need a perfect drill for, it is drilling glass. (Lamp shade holes).
I've drilled through 3" of steel before with no issues.

I have a 1950s era Atlas floor drill press with 1HP motor and 3 pulleys but generally leave it at the slowest speed. I love old iron. Walker Turner, Delta, and Powermatic made some great floor model machines. I like the older stuff made in the USA

I'm in the market for floor model myself

I a table top one now, Larry donated to me, skillz maybe (red) thing works great, I've drilled some 2" thick boards for projects and use it for all my plug stuff

get a floor model
worth it
like Paul said, try craigslist you might find a deal

Jet an Delta make some nice floor models Ross. Just watch the throw adjustments on them. Some of the newer ones all but need to be glued to keep them from moving out of adjustment. 5/8 models will do what you want . Craigs list is the place to shop. Loads of stuff up this way at good prices.

There is a used machine tool place in Pawtucket that has several used floor model drill presses in stock.. Go to Craigs List and seach in tool section used drill press.

here is one of several listings by this guy in Pawtucket
