Thread was titled "Alternative to BitInstant".
BitInstant does not sell Bitcoin at $17 over its market value.
Still looking for an alternative to Bitinstant.

There is no exact alternative currently.
You need to do deal with individuals on bitcoin-otc or here in currency exchange section, if you need bitcoins at marketprice.
Ps: if you are worried about getting scammed, use a escrow.
