Seems like an abundance of bad reviews mixed with good reviews on Amazon. Mine has worked flawlessly.

You take your chances. I think I paid about $130 for mine in 2008.

How well it lasts is probably going to depend on how well the lead-acid battery is taken care of. Run that battery completely down a few times, and you may as well throw it away.

I build all my own equipment, so I won't be buying one, but it is good to know about it.
