Aftermarket eBay powersupply for W510

[SparcV]

I'm looking to by a second power supply I can leave at work, and I was looking at these $55 aftermarket power supplies that claim to be 135 watt and compatible with the W510. I was wondering if anyone here has tried them yet?

I think its ridiculous that Lenovo charges $99 for one.

I purchased two extra 135 watt units at ridiculous prices and they will not be here till end of month. If you have a 90watt left over from another Lenovo, it works just fine for every day computing.

I here on the ridiculous pricing. If it helps I got mine from PCConnection.com for 89 a piece
