BTW- kinda proud of the group this mournin--
Nobody has jumped on the OP for wantin a dremel
I viewed this earlier at zero replies. I didn't provide an answer at that time because I got distracted. dog, coffee, heat.
I have two models
1) Dremel Variable Speed with two collet chucks and an adjustable chuck.
2) Black and Decker variable cordless with adjustable chuck. (with removeable, separate charging batteries).
I have several cotton wheels and a couple shaped like a bullet (rouded conical ogive).
The cotton attachments used with Flitz is the only real use in gunsmithing for me. for light polishing only.
I think that the adustable chucks are a must if you think you will be changing accessories often.
I have the flexible shaft, but can't say that I have needed it yet.
In additionion to the set of wheels, drums, bits, tips and stuff, I also have the router base, grout remover and chainsaw attachment.
The only attachment that I use regularly is the chainsaw sharpening setup.
I'm pretty good at a quick touch-up and a full resharpen. Beats a trip to the saw shop. Obviously the corded model is best for resharpening (unless you have a pocket full of batteries)
I would recommend that you stay with
Dremel brand, find a package with accessories priced right for Christmas.
Stay away from any low-end unit, such as the little Harbor Freight unit driven by a wall-wart (AC adapter), they lack power and will drag down easily.
ONE MORE THING. Try to find a version with a
flexible cord, some cords are stiff and make delicate tasks more difficult.
