I'll start, I guess.
To set the stage - I took a few days off a week ago for some R&R. My wife had other ideas, and I had to install a wet bar made out of nice cabinets, built in fridge, wine cooler, sink, etc. But I like doing this sort of thing, especially a last minute-hurry-up-and-get-it-done kinda thing. Besides, I'm proud of it.
To preface the work I did, my wife declared that this was the only project all summer, allowing me to go boating all summer. Ha! Did I get suckered in. So now I have to replace the front door with a fancy cut-glass affair. So, since I am now buying anew door and storm door, I figure I'd better get some nice hardware. My neighbor has a PowerBolt dead bolt. This is a battery powered key less entry scheme. So I go to eBay to see what they cost, and they are about 70 bucks. Not Bad!
But then I see something even neater - a biometric key less door lock. That's right - fingerprints! It stores over 300 finger prints, and also has a keypad if needed, and even a security key. So I bought a biometric door lock for my new last-job-of-the-summer door. I would never have even have looked for one.
My wife says I'm nuts. But I figure if I keep doing goofy stuff like buying fingerprint readers for my front door, she'll lay off the projects.
PS - I buy a lot of stuff on eBay, and sell some stuff too. Never had a problem with eBay or PayPal, knock on wood.
