All true Paul, but RS is a bit different, it's not just another version of the same tool, it's a different tool.
Since it isn't a hot iron, there isn't an issue with surface area/heat and there's no pre tinning. The tungsten points I used were as sharp as a compass point and only need to make an electrical contact, not a heat bridge.
I sold mine off before I started SMD soldering and the way I'm going these days with Arduino and the like, I'll probably get another setup (or buy mine back, hint hint). Instead of having to limit the contact time with the iron, you can hold the point in place indefinitely, then depress the pedal and it's done in less than a sec. Never gets hot enough to burn the component as opposed to me with my Hakko. Currently I need to use a jig to hold the SMD LED, tape the pre tinned wires down in place over the contact points, add the flux and hope I'm not there too long with the iron. With the RS, I could hold the wire in place with the probe, flux and zap.
I think I just talked myself into getting another.
