I bought the Screwfix jig & found the plastic stops turned brittle & broke after a year. It was poor quality plastic. With 3 different templates its a lot cheaper but check those stops & if possible get someone in a machine shop to make you a set of steel or aluminium stops to fit. I also found that the plastic hold down knobs slipped out when the plastic was failing. Unsafe as the workpiece could move.
I paid £70 for the 1st jig then another £50 for a replacement. It would have been cheaper to buy a Trend DJ300 at £100.
I see that Trend now do the CDJ300 jig which is listed at £70 so is a much better option that the one I bought which has now cost £120 to make 2 drawers.
Trend are known for quality so I have fast come round to the way of thinking that buying cheap tools to get started is a much more expensive option than buying good kit to start.
It's noticable that Trend are fighting back at the DIY sheds cheap own brand routers by introducing the T3 & also as a complete starter set with router table for £150.
