Well I'd say stay away from Kits like Shapako they are far too weak IMO and not very well designed. I've not seen any Kit that's worth a damn.!!

Equaly you don't need to go OTT like Boyan with 100mm tubes for simple router.

So really the thing you need to ask your self is what do you mainly intend to do with the machine.?

Budget is also key because the honest truth is that you get what you pay for and to have decent machine that will be hassle free and cut correctly with good finish cannot be done on the cheap.
