re: Buy Factory For $3.00, or Build Your Own For Only $3,500.00

Funny, yes. I've done much the same. The "average" family moves about every 5 years, or at least this used to be the case. Next family will inherit the old crap, with no warranty. People used to own cars for about 5 years on average, as well. Sears had a lifetime warranty on batteries. I know a guy who took his car in several times for a replacement battery under that warranty. Sears depended on people selling their cars before the battery needed replacing.
