Ummm. . . .I've bought literally tens of thousands of dollars in home audio/theater equipment and computer equipment - usually ordered online. I have used both FedEx and UPS and have used every class of service from ground to next day morning service. I only had one problem with either of these companies that I can recall - a package was delivered a day late and I received a full refund for the shipping. UPS, in my experience, is pretty good at what they do. FedEx is somewhat better in some regards, but not in getting a package to the destination when they say they will do so.
Regarding the tracking number issue, if you order ground shipping, UPS does not scan the package very regularly. It goes on a truck and stays on a truck until it gets to a distribution hub. Thus, there are usually not many updates. As far as not receiving a tracking number, this is not UPS's fault. The tracking number is on the address form that PCTorque prepares for shipping. It appears to be PCTorque's policy to not send the tracking number to the customer right away - they only do it the next day after the package ships. Thus, if you order next day air, for example, then you may get your tracking number after or a short time before the package is delivered. This is what happened with my order - I used next day air, the computer shipped on Tuesday, I received the tracking number via e-mail early Wednesday morning (~9:00am, I believe), and the computer was delivered at 10:30am. If for some reason PCTorque doesn't e-mail the tracking number to you the next day then it may be possible, even with second day air, that you may not receive a tracking number before the package is delivered. But I don't think this happens very often that I have heard.
Other online retailers use systems that automatically send out tracking numbers to their customers when the number is issued by UPS/FedEx (for example, Amazon.com, although other small retailers also do this). However, you might want to ask yourselves whether you want PCTorque to invest in such a system and build the cost of that system into the price of the computers. I think I can live with an e-mail tracking number a day later for the lower price.
