Matt, welcome.
You have a lot of good choices with Axiom, if you were to ask them they'd likely ask what size of room you'll be finishing, your preference between music and movie viewing, TV or Projector, etc. and then they'd suggest an appropriately sized unit. Listening to them may save you a pile of cash. Me it was go big or do't buy and I've no regrets.
The room dimensions help alot here, for me, so this would be interesting to see what you have in mind.
Many of us live off this stuff, exited to see someone else jump on board and "hear what they've been missing".
