I prefer Bandicam. It has options for various codecs - lossless and lossy - so you can choose the best compression / quality ratio to suit your needs. i.e. MUCH smaller files than those created with Fraps. You can try the unregistered version for free to see if you like it. The unregistered version of Bandicam can record for up to 10 minutes, unlike the 30 seconds that Fraps gives you, which may be all you need.
