You are deffinitly gonna want a Royal!!
I will try to answer all ur questions,but feel free to PM me if needed.
Royals are best off learning to feed on frozen.(read up on how) I feed mine on live,but it is very risky!!
Royals are very docile and great for first time. Remember tho, as far as letting them just have free range.....they DONT WANT IT!!! They want to be confined in a 'terarium' that suits their size. (read up on the proper size)
They can be picky eaters and 'take breaks' in feeding.
I cant remember any other of ur questions,so feel free to PM ME with anyting further.
