Mtgox can do LR transactions easily so it doesn't make sense (getting to LR requires a significant amount of money to be cost effective).
You should also add details of the amount of bitcoins you have and your fees to the main page.
I am still unsure about Liberty Reserve for that reason.
I'll try to add balance and pricing to the front page in the next couple of days. For now you can see that info at

Well MTgox has a min coin purchase of 100,
so anyone who can offer small amounts with via Liberty Reserve,
would be very useful.
