Plunge routers are my main tool and the only Bosch 1/2" one that I've owned had play in the columns so I sold it to someone who wasn't critical. Apart from the Triton TRA-001 in the table, all my routers have been 1/2" Makitas which all have an excellent plunge action and NO play in the columns. They also have a LARGE opening allowing full view of what the bit is doing. A wide selection of template guides are available and in any case are relatively easy to make, unlike those for the Bosch which have a bayonet fitting. Collet reducers are available to take 6mm,8mm, and 10mm bits, these adaptors are suitable for ALL 1/2" collet chucks. I always recommend around 3hp as these will do everything that a lower power one will do plus a great deal more.
