I was wondering if someone has purchased something from the following sites:

http://www.laptopabc.com/
http://www.laptoppartsshop.com/
http://www.upgrademaster.com/
http://www.laptops-upgrade.com/
http://www.terrabattery.com

What can you tell me about those sites, reliable? good customer service? etc. or if you know a reliable site post it.

I'm in the looking for a new power adapter for my Dell laptop, and they all offer the adapter for $25, whereas at dell.com is at $65.

Thanks a lot.
