the Bosch I was talking about was also the GKT55, not the GKS.
Although I've never used any of these systems, it seems clear that Festool tools work as a system, and for professionals that is definitely an advantage. I would almost certainly buy Festool if I were doing this professionally. The extra 30%-50% or so over the Makita and Bosch would be perfectly justified.
However, as much as I would like to get a Festool router, jigsaw, etc, that is not going to happen, as I already have those tools (other brands) and couldn't reasonably justify buying new ones.
So, all things considered, seeing as there are no significant differences between the
1-Makita set (systainer+saw+1.4m track),
2-Bosch GKT55 set (systainer+track+saw) and the
3-TS55EBQ-FS plus (the EBQ has the brake and var. speed features, as do the Bosch and Makita, correct?)
price is going to be the deciding factor.
The best I could find so far was £371 for the Bosch (powertoolworld), £295 for the Makita (from tools4trade and £300 for its) and £451 for the Festool (Axminster).
Or if buying from Germany (check idealo.de), 401€ (~£341) for the Bosch, 346€ (~£295) for the Makita and 514€ (~£438) for the Festool.
So unless I'm missing something, the Festool is roughly 50% dearer than the Makita and 30% more than the Bosch.
Are there better prices than these?
Please bear in mind that I'm not in the UK, so I have to buy online and don't benefit from free p&p.
