Thank you all for your comments. I'm new to these sort of forums so I'm not sure if you all get notified of this new message I'm now writing. Yes, I suppose I went for the Dremel again as it's what I know and I was in a bit of rush and it was easy to just order quickly based on needing it this week to finish off Christmas orders without adding a load time on my manually buffing with emery boards etc but I would have researched if I had time. It's great that some of you have recommended the Foredom as maybe I wouldn't have stumbled across this. I'm thinking I may order one of these in any case...

I googled it and found the "Foredom Motor SR - Pendant/Hang-up with Flexshaft" which I'm guessing is the one you're mentioning. Do these tend to last a lot longer than the dremel? I'm a little rubbish with new tools like this but guessing you can still buy the necessary chucks or whatever to hold whatever sized mandrels you need.

Thank you so much for your help x
