The finder is also a budget choice. It is a red dot model. But that is also OK since you will only use it when first aligning the telescope.
The star diagonal works pretty well, and it is an important part. Smart move from Celestron.
The focuser works surprisingly well, considering it moves the primary mirror instead of the eyepiece. Although it causes some image shift, it is hardly noticeable.
Celestron did a good job with the accessories. There is not a single part that is unnecessary that drives the price up.
