QRS - again!

QRS Inc. (QRSI) has received another offer - its 4th (5th if you include the one from JDA) - from a private equity group. Details were not disclosed.
I am still not sure why QRS is drawing so much attention.
Meanwhile, a few other players are worth a look :

• Retek (RETK) : is worth buying at its current price. I don't own any, but am planning to add soon. Someone is probably seriously evaluating buying them currently!
  
• Manhattan Associates (MANH) : This one looks expensive, so waiting for a pullback is a good idea before jumping in.
  
• Manugistics (MANU) : is trading at near-alltime lows. They got a new CEO recently who is known for turning around companies. I own a few, bought at levels higher than the current value. I am still planning to add more - i think this will be acquired within a year or two, but not before it sees a substantial appreciation in value.
