Look at BC Longboards, I own the eel and I love it. Its 41'' so its a solid size plus its made of bamboo and fiberglass so its going to last you a while. Eventhough its $230 for a complete you get paris trucks, orangatang wheels, and reds barings which are all solid to be included for that price point.
When it come to riding, its perfect for everything. I got in a sketchy accident (before I got the board) so I dont bomb hills as much but you would be fine bombing on it. Its also perfect for just goofing around and cruzing. Its shape allows you to do tricks and stuff like that and I rip it around my campus all the time.
I got it as my first board and am soo happy I did because i'm not gonna need another board anytime soon and It looks dope. All my friends prefer it over their boards and one of them has an origional longboard which he paid a good $100-$150 more for.
Just go for something cheap, but nice.
Flush mounted trucks are really nice especially when you're starting out, they allow you to be a little bit closer to the ground which helps immensely with establishing balance and other basics.
