Xiaou, you have no idea what you are talking about. Please do some research, then you may have an educated opinion. High end jigsaws, when used properly, can produce at or near finish product cuts. I have seen enough video and photo evidence to prove that unquestionably.
Anyways, I had to work on the pacman project ASAP, so I went with a $60 orbital Skil saw that I will probably take back. It is significantly better than my standard cheapo B&D, but isn't 'that' nice. The blade stabilizing system isn't very good, and you can't dial in a cutting speed like nicer saws, even though the trigger is variable. I was recommended the Hitachi jigsaw, which I was told that many pros in the area use. It's a little cheaper, and may be a good compromise - also has a nice warranty. The Skil Saw was worth a test drive though to better convince me that I would want the nicer jigsaw.
Besides, the hitachi is currently at $64 on amazon - nearly $30 cheaper than Lowes, and on par with what I paid for the Skil.
