Availability of spares and accesories is a great advantage of the Trend tools.
I use a Perles router which Trend copied for their original T5.
Trying to get spares from Switzerland is difficult but everything made for the Trend fits a Perles perfectly.
DeWalt use the same fittings unlike many who have individual sizes making them useless when a new model comes out.
I don't have a T3 but a Bosch POF500A, its only 500wats and fixed speed. I also have a Trend dovetail jig, the old one. I have both 1/2" and 1/4" combs for it and have cut quit a few dovetails using the POF500A.
The one thing I have done is had made an adaptor to allow the Trend fine height adjuster for a T5 to be used on the POF500A, very useful for tweaking the fit of the joint. :shock: Look in the gallery for the HiFi cabinet I made, all of the draws are made with 1/4" dovetails cut with the POF500A and Trend jig. :lol:
The T3 should work with dovetail jigs just fine as long as you get the correct collar size for it - should be no problem from Trend.
I have a T3 and a T5 and both are superb. I really only use the T3 for cutting small groves for inlays though
Dr. I find that Trend router cutters in their craft range are amongst the best one can find. I use CMT, cheap ones that came free with other routers and Freud Pro and the Trend and Freud are the best and about the same - Freud costs more though
