I've got Bosch POF 500A and 600A (which is the 500A but with varispeed). I think the Trend T4 was based on them. They have really good Swiss-made motors, BUT...
... the depth setting and the plunge generally is a bit crude. They can jam, and there's enough give in the two plunge guides for the depth setting to be "approximate."
I like them for their light weight and willingness on the bench top, but I've used them on door frames (with a home made jig) and it's always been a bit of a heart-in-mouth moment, in case I slip and gouge something accidentally.
The Makita looks really nice, especially with the fine depth setting choice of bases and that long side handle (good for vertical use). But it is also a LOT more expensive than a POF 500/600A secondhand off eBay. I'd go Bosch over Trend, but Makita over both, if I could afford it. Bosch, incidentally, do have a similar offering now to the Makita (my POF 500/600s are long obsolete), and I think it's a bit cheaper, also DeWalt and Draper - might be worth a look too. People have said the Draper is good value but I've no personal experience.
