Hi Kayne...and welcome to IIS!
Mate, I started viewing with a 76mm Celestron First-Scope, for which I paid $150! Your Powerseeker would be better than that and for $40, you're a winner! Don't worry about not finding anything, you will definitely get used to things quite quickly if you give it some time and practise!
I upgraded about a year ago to an 8" Dobsonian; after sorting yourself out with the Powerseeker, it would be well worth considering an 8 or 10" Dob - Dobs are VERY easy to use and provide smashing views of just about anything up there!
The only reason folks generally tell beginners not to buy a 12" Dob is that they are very heavy and bulky BUT I must say that by the time I bought my 8", I could have just as easily handled the bulk of a 12" and found it about as easy to use.
Anyway mate, don't want to confuse you - just enjoy the new hobby and savour those first moon views...awesome!
