@Theearthspeaker-Cheers for that mate-I've got a multi-tool Dremel (can't remember which model) and am now considering one of these, as they are available in the UK. I'm just going to do some detective work to find out as to whether a guide(with plate) is available, otherwise my lines will be all over the place .
Bits for the standard Dremel multi tool are cheap enough and readily available also. Even non Dremel parts seem to work just dandy.
Alternatively, there's the Dremel Trio which, on paper, seems like a wonder tool. I've read however the bits are non-standard and tools (such as router bits) from another Dremel cannot be used with the Trio due to the collet size. Still, it does look nice if a 'little' expensive...still sales after Christmas and all that, I'm just not sure any 'unnecessary expense can be justified atm.
I'm also just not sure what size or type of bit comes with the Trio. After all, I only need a straight bit for the time being as long as I can work to a plunge depth of 2-3mm I'll be happy.
Then again I may just go cheaper, buy a bog standard router etc and take it from there. For what I'm going to be using it for (2, 3 and possibly up to 6mm MDF) I don't need industrial standard.
As long as router bits and blades for the various models of tools out there aren't mega bucks, I really don't mind.
A third alternative is that I forget about routing a channel and stick with quality glue and butt ends for walls to floors with small panel pins on the reverse. Oh Santa, what is a boy to do....
