It's a new week, which means it's time to check the most interesting insider purchases.

After reading through numerous filings using insider tracking tool Form 4 Oracle, here are my top five this week.

Is the price right for Cost Plus?
Ask any of my Foolish colleagues and they'll tell you: I loathe turnaround stories.

So do most of the professional and amateur stock pickers in our Motley Fool CAPS investor intelligence database. Look at how they rate ailing retailer Cost Plus:

But that's the group. Some see a turnaround in the works, including Morgan Keegan, a CAPS All-Star that, today, upgraded its rating for Cost Plus. Why? Valuation. Cost Plus trades for just 68% of its tangible net worth.

Insiders are equally optimistic. Three of them have spent more than $89,000 on stock since last Tuesday. Board member Fredric Roberts, a retired investment banker who has been a director since 1999, led the buying when he acquired 5,000 shares on Friday.

Color me intrigued, but is there any actual evidence of a turnaround taking place? CAPS investor teasdale100 seems to think so, citing improved inventory management. He may be right. According to Capital IQ, Cost Plus turned over its inventory 2.9 times last year, up from 2.6 the year prior and the best performance investors have seen since 2003.

That, in turn, may have impressed creditors. On Monday, a group of financiers led by Bank of America (NYSE:BAC) agreed to provide Cost Plus with a $200 million credit facility secured by inventory and receivables.

Or, in simpler terms: Cost Plus may not be out of the woods, but at least someone is willing to lend the retailer a compass.

EarthLink to Rolla
Fools haven't been too kind when it comes to Internet service providers, either. EarthLink especially. Here's why.

Mix in the tragic death of former CEO Garry Betty in January and a still-bleeding subscriber base, and, frankly, there just isn't much to like about this one-star stock.

But don't tell that to new CEO Rolla Huff. On Monday, he spent $725,000 of his own cash to build a stake in his employer. His reasoning? He didn't give one to my Foolish colleague, Anders Bylund, saying only that he doesn't "put down three quarters of a million dollars trivially."

Huff's swagger makes me curious, but with less than 3% of EarthLink still in the hands of insiders, they've nowhere near enough ownership interest to make me a buyer.

Actually, it's worse than that. Save for Huff, insiders are cashing in. Donald Berryman, the company's executive vice president of municipal networks, is only the latest. He sold his entire direct stake a month before Huff bought his shares.

For me, All-Star CAPS investor cobradon best sums up EarthLink. Quoting: "Falling margins, falling market share, increasing debt. There's not much to like." I'll say.

That's all for now. See you back here next week when we dig through more insider deals in search of the next home run stock.
