yeah I'm still around...
I got my tint off ebay about a year and a half ago. It's 20% tint and I'm fairly happy with it. You can still kinda see into the bus if there's light inside (at night or when it's not real bright out) but when it's brighter outside than inside you can't see in.
I think I paid around $60 for a 100 foot roll shipped. It seems to be holding up well, the only bad spots are where something scratched the tint from the inside, mainly int he back where I put the grill, or bikes and whatnot when taking long trips.
I don't know what kind of tint you'd call it. It's just regular window tint.
Here's a link to some tint on ebay

that's the same guy I got my tint from, looks like you can specify what %tint you want. I got 20% and like I said you can still see in at times. If you got 15% or 5% It would be a lot harder to see in, if I did mine again I'd try the 15% although less sunlight would get in.
Anyway again I recommend that you get a wider shorter roll than I did... I got a 20" X 100' roll. Since my windows are each about 10.5" tall (each piece of glass) I ended up with 100 feet of 9" scrap and I ran out - I had to buy more at a local store to finish the back 3 windows. I'd get a roll at least 24" wide and 50' long.
Here's another post about window tint...
