I have a high end dremel, I also have the long wand attachment that allows allows you to work without holding the bulky dremel. I am sure you know what attachment I am talking about.
I have an accessory/tip kit that has 145 pieces and a sharpener. It has polishers, griding stones, router, drill bit, sanding disks, all kinds of stuff....and I have only used the drill and one sanding tip. The rest are totally unused.
Model number is 395 Type 5 and works perfectly. Very much low time used. I only used it to sand/smooth out holes that I cut with a hole saw when I would install a clear jewel and LED ring. That's it. I used my drill for the hole saw.
Make me an offer if you are interested. I am not sure if you were looking for one this good.
THis is the flex-shaft (wand) attachment I am talking about in case you didn't know:http://www.dremel.com/HTML/home_fr.html
Click Attachments, then flex shaft.
The dremel I have is about a year old. At the time I bought it, it was the highest rated one in Consumer Reports magazine. I thought I would be doing a lot of case modding so I bought the best rated one.
