My last machine needed it, so I got pdf995 and it works fine. Two versions available, the freeware has ad's inserted (but you can ignore them) and the $9.95 version has a few more features and no ads.
All of my PC's are purchased used. I run what they've got when I buy them and I fill in any gaps with cheap or free ware which works fine for most casual users. You only need the high-end stuff when you've got complicated details- most people overspend for it and don't need or use the expensive parts. Go with your needs and read off-site reviews before choosing- popular doesn't always mean better or necessary.
