Lone Star stock buyout offer for Accredited Home Lenders (LEND)?

Lone Star has offered to purchase common stock shares from shareholders for a little over $15/share for shares of Accredited Home Lenders. As a shareholder, I'm not certain as to whether or not I should take this buyout or not? Any feedback would be appreciated. I'm looking at this stock longterm. I've already made over 100% on the stock since it hit the skids back a few months ago, but I'm curious to see how high it will go after all this subprime stuff blows over and the mortgage market gets back on track. Your thoughts?
