Hi Murat,
As a very new astronomer but getting senior in years also I jumped in with a second hand SCT which I enjoy heaps as I do want to develop my imaging skills. However I have to admit to spending time with the wifes 8" collapsible dob last night and enjoyed M42 particularly to the point where I'll have to get another ep for it methinks. I'm honestly thinking of getting a bigger dob to take to star parties and leaving the SCT setup in the obsy ( when I get it that is eh dearest wife
) because the dob is just so user friendly for the visual observer. Advice given to me earlier this year when starting out was to get the best scope I could afford and let things develop from there Good luck which ever way you go.
Dave
