I got the same soldering kit because I couldn't find my old Weller gun. It works just fine and the doodads that come with it are nice. (Of course, buying a new one was the only prerequisite for finding the old one but such is life
I looked at my local HF for the little $3.00 robot man but all they had was the $7.00 jumbo helping hands model that comes with a monster of a magnifying lens that contains a pair of the LED's the Chinese are so fond of. These run off 3 AAA batteries and are supposed to suffice as work lights. Actually, this magnifier/illuminator contraption makes the entire unit inconveniently top heavy even with heavy cast iron/felt padded base/parts tray and handy-dandy soldering iron stand. It always seems to be in the way and the LED's are pretty much useless. It now resides in the box. For a work light, I use an old timey high intensity gooseneck bed lamp and for magnification, I use my old DA-5 Optivisor.
10-4 on the rotary tool. I don't have a cordless one but a big ol' Craftsman flexible shaft tool. I've used it on every mod. It's a pain to haul out of the case and set up. I have virtually every type of diamond cutting tool under the sun for this thing. Most of my various diamond points, blades and wheels came from HF. They have a great selection of diamond tools for dirt cheap and they hold up very well... even when using them on granite and metal. I use the same tools year after year.
