I usually buy from Dell's outlet but they had nothing available like what I needed - a basic PC to replace my old one that died unexpectedly.  I looked here on Amazon and found this company which had good reviews here and on other sites who rehabbed PCs and resold them.  I took a chance.  I've been using it for weeks now and it's performing brilliantly.  I'd recommend both the type of PC for those needing just the basics as the price is better than new and the warranty is as long.  I'd also recommend the rehabber/seller as they did a good job with the PC and a great job packing it to survive the shipping process.
