Was looking to buy a Dremel, but the cost of them is somewhat beyond my budget. Browsing in Homebase I found this little set with loads of attachments.
It's certainly no Dremel, and fitting the attachments is a little fiddly. However, it works perfectly well and for the price, and the number of times I need to use it, it's great.
£39.99 in Argos. If you want Dremel, then expect to be paying around £100.00 for a similar sized kit.
