Trustworthy IDE HDD Retailer

I've got an old Gateway MX3560 that's been great to me, but now it needs a new IDE HDD and LCD inverter. IDE drives have become scarce in the past few years, and I was curious if you guys had any RELIABLE sources for them. I've looked on Firefold, TigerDirect, and NewEgg because I've shopped there before but I'm looking to really compare combinations of speed, size, and price. Any additional suppliers that you could point me toward would be greatly appreciated!

Thanks!!
