The way to go now, especially if you plan on investing < BTC2,000 is one of the many pirate pass throughs, on GLBSE you can find the PPT issues that have a 25% insurance from 6 high rep guys & pay excellent interest on a 4 week bond, there is also goat's TYGRR.B-P paying about 6.6% (if you buy @ 1.02) - 6.8% per week. Lenders forum has PAYB.TC - Bitcoinmax with the best rate of 6.9% on any amounts over BTC10 per week, see Starfish/Patrick's 'Who offers what' 'Who Pays What' thread for others.

Edit @m_yaw If you do happen to wish to invest > BTC2,000 & plan on leaving it there for at least 3 months then feel free to PM me re a possible referral with a little more info about youself & what you're planing/hoping to do, thanks.
