Hi Gigel and welcome. You can mount almost any router to any table top. The only issue is if the bolt pattern on the router is smaller than the center hole(s) on the table insert plate. You are usually only likely to have that problem if you are trying to mount a trim size (smallest size) router which is not normally recommended. Most of the members here would recommend that you use a router of at least 1100 to 1200 watts. If you will need to use it as a handheld router at times then we would also recommend that it be a plunge type router. A plunge will do everything that a fixed base router will do but the reverse is not true.
If you get a discontinued model router then if something goes wrong then you will not be able to get parts for it. Some parts can be bypassed such as speed control modules. Collets are also an issue but if you stick with well known and popular brands like Makita or Bosch then there may be after market replacements.
