Hi Col,
Basically those machines are a PITA, having to adjust the screw at the back to change the blade and readjust the tension. I have a Ryobi one that has been modified to a quick release, which is what ideally should have been done at manufacture. The Record one is basically a rebadged Ryobi with a color change. These units are OK if you're not changing blades or fitting through a drilled hole cutting out small pieces, you'd get peeved off very quickly doing intricate work.
Would it be possible to put in a few $$ yourself to get a better unit with the quick release, something like this, though nearly $700.00
