Hallelujah, it's Friday. Let Gearlog start your weekend off right with these tech bargains:

1. Once again, Amazon's Friday Sale has a bunch of great deals. Save 53 percent on the HP M737 Photosmart Digital Camera. Originally $215, the 8-megapixel camera is only $99.99. The camera has a 3X optical zoom and a 8X digital zoom. Hurry, the offer is only good until the end of the day.

2. This next deal is for the true Cheap Geeks. Woot.Sellout is selling the Mio DigiWalker C310x 3.5" Portable GPS for only $59.99. The GPS system has a list price of $195. But, here's the deal: this product is from 2005, and therefore, is loaded with 2005 maps. Don't get discouraged, you can hook it up to your PC and get 2007 maps from the included CD. I realize it's almost 2009, but Woot.Sellout casually says that the real value of the Mio is in hacking it: "Nice solid hardware, decent 3.5-inch LCD screen...with a little know-how and the right tips and tricks, you can even load it with Windows CE and use it as a PDA."

3. If you want to annoy your co-workers in a cheap, secretive way, then the ThinkGeek Annoy-a-tron is exactly what you need. From now until midnight on December 7, the Annoy-a-tron ($10) is free with purchases of $25 or more. What is the Annoy-a-tron you ask? It's an easily-hideable, simple device that beeps sporadically, annoying the pants off of whoever's nearby. Enter the code LUNATIC during checkout to redeem your free Annoy-a-tron.
