There's no 90g setup, I used the 90 stand for my 45 since the tank has strange dementions and they only other stand that fits is the JBJ one which is built like crap. If anyone needs more pics of the stand or anything else send me your email or cell number and I'll send them.
Of course not since it's a year old and only $200. I don't see why anyone would need an HD version, just another gimmick to charge more money. I never needed to add more power to any of the channels I was using.
