Hey Ken,
we have a search function here. You may have found that
-
the only options currently possible with the Onefinity are 65 mm routers (so the Dewalt or the Bosch won’t fit) or 80 mm for spindles
-
there exist countless counterfeits and clones of the Makita RT0702C and Makita RT0701C routers
-
the Makita hand trim router and most of its clones have a proprietary collet system that holds the bit only at the front of the collet and with which bit holding issues are common
-
That there exist Makita hand trim router clones with real ER collets.
See here for comparison.
Note that for a spindle or router for ER11 collets, you get collets for bits with 1 to 7 mm bit shank. That means with a ER11 router or spindle, you can use bits with a 1/4" shank by using a true imperial 6.35 mm collet or a normal 6.5 mm metric collet, but bits with a 3/8" (9.5 mm) or 1/2" (12.7 mm) shank cannot be used with a router or spindle for ER11 collets. For 3/8" (9.5 mm) bit shanks you would need a router or spindle for ER16 collets, and for 1/2" bit shanks you would need a spindle for ER20 collets which will take up to 13 mm bit shanks (1/2" = 12.7 mm).
