I got mine 20% all around. I dont think 20% is legal in Maryland (but no one really cares). I live in MD by the way.
My friend's dad owns tint shop, so I got mine for $110 cheap, but GREAT WORK!
normally they charge you about $160 and up + warrenty

here are some examples, hope it helps
- Celica - 20% small sides 35% bigger side window
- Accord - 20% all around









Just took it 20 mins after I read your thread.
Good luck with your tints!
