NEW YORK ( TheStreet) -- Commodities have become so overheated, it seems investors will go anywhere and risk anything to try to take advantage of the monster moves.

Recently, we saw another small commodity fund, Peak Ridge Capital, go bust and get sued for $40 million dollars by Morgan Stanley ( MS), its broker and clearing dealer.

What's interesting about Peak Ridge is that it's connected, at least marginally, to a great rogue of commodity trading, Brian Hunter.

The same Brian Hunter sank the enormous Amaranth fund in 2006 with natural gas trades that cost the fund almost $7 billion dollars. This was by far the largest blowup of an independent commodity fund on record.

From Amaranth, Hunter managed to raise capital to try again at his own fund, Solengo advisors, which went bust as well. Its assets were bought by -- that's right -- Peak Ridge.

It was in natural gas trades that Peak Ridge got caught and was unable to meet margin calls -- trades that Peak Ridge "adviser" Brian Hunter specializes in.

I outlined Hunter's history today on CNBC's "The Call" with Melissa Francis.

The obvious question from this latest fund blowup is: Why do investors continue to throw money at dangerous funds run by risky traders?

The next question is: If the desire to be engaged in super-hot commodity funds can overcome all reason, what is the proper way (if any) to try and gain access to the big run in commodities?

There are three ways to directly gain access to commodity prices for retail investors, and each has positive and negative aspects.

The first is commodity index funds. These have the most direct correlation to commodity prices and track baskets of commodities using futures markets and over-the-counter contracts (swaps) to try and correctly mirror the motion of all commodities. PIMCO's Commodity Real Return Strategy fund is an example of one of the biggest of these.

The biggest problem for retail investors is the high minimum investments most index funds have. They are largely created and run for huge institutional portfolios, pension portfolios and high-net-worth investors. Many have a $100,000 minimum or more.
