[Help] Newbie trying to set up home router and AP.

Hi, I am sorry if this is not the right place to ask. My wifi router just died and I am planning to go for the Edgerouter 4 and the UAP 6 Lite instead of a consumer wifi router. Is it the right combo or am I missing something ? I have never setup an Edgerouter before. Is it difficult? I tried to search for Edgerouter 4 setup tutorial on youtube but most of them are for the Edgerouter X. Are they pretty much the same ?

I have mix feeling about them. On one hand I am excited about the new system, new toy. On the other hand, I am afraid that it will be too difficult for me to set them up.

Is there any guide/tips for setting them up? Thanks.
