I purchased a Veritas #05J25.01 Router Table Insert from Lee Valley.
Since we have more than one router the decision was based on price not
the easy removal and use with insert attached. The supplied jigs etc.
were great and the installation went smooth. The height adjustment
must be made on the router so a table top crank would be good but we
rarely ever change the setting so that wasn't worth the expense here.
Just thought it might be of interest to someone in the market.
Thanks again to all that had replied to my original inquiry!
