My 5 year old HF is way to fast for metal. Slowest speed on it is 620 rpm. Can someone recommend one that has a better speed range for a tabletop size?

For the sake of conversation your speed really depends on the diameter of the bit. Although it is not ideal my benchtop drill press does 600 something also. Drilling 1/8" holes is fine with coolant, but over 1/2 it gets hairy. I got one of those one flute step drills and it works pretty sweet in 1/8 stock or less for fractional holes.
Just throwing this out there, how big of a hole do you think you will ever need to drill?
You can use higher speeds to drill bigger holes if your setup is rigid, you have stuff clamped good, and use a lot of coolant.
HF has a $129 benchtop that goes down to 250--had I know about needing a slow speed for steel, I would have paid the extra for one rather than the 5 speed 650 rpm ultra-cheap one I did buy. I've ended up having to use my hand-held Dewalt to do bigger holes, even with cobalt bits.
