Welcome along, enjoy!
If you are able to take someone along with you who knows about gunfit, then do it. But be careful, a lot of people claim to know, but know squat and could screw the whole thing up for you! Close enough will do at this stage, but get someone to check.
If you stick with the usual suspects - Mirook, Beretta, Browning - you'll unlikely lose much money, if any, when you trade it in - and you WILL trade it in! The bigger names will call you in your sleep! You'll accrue more knowledge, see more pretty irons, try a few and fall in love. Then you'll consider selling your children or your wife to get to the big K, or P! (I recommend selling the wife first, because she'll complain about how much you're spending on shooting, that you're never home at weekends etc etc).
Someone who lives nearer you will be along soon to recommend a good shop/coach/smith in your area to help you choose. Good luck, and happy shooting!
