I bought the LF1/FS (FS stands for foot switch) the two things I liked about it were the substantial build quality, and the table that allows you to clamp vertically as well as horizontally. There is also some ability to angle the table that gets most if not all angles ever required.
The Foot Switch is a real benefit, one hand on the vice / work, the other feeding the drill and the foot switch to turn it off rather than risk pulling the drill out whist turning.
I bought it as a project as it needs some work....new motor, motor pulley etc.
I recently bought a MF4/MK3, which I put a silky bid on eBay and won. This drill is a real work horses and an order of magnitude again above the LF1 / Drill through. However, for virtually every requirement they are all excellent, superbly manufactured and last generations.
