I fully agree with Vitaliy but like to add some ideas.
If you are mostly purchasing the same brand, you probably have a set of drivers for each of the series that you use in tools such as SCCM or similar. You can add those already to that recovery media that you built upfront, and only rebuilt it when you deploy newer driver for the network (wifi also), USB and storage devices. You can also create a few of those as ISO's and store them on your file server. When needed, I burn them to a flash device with windows 7 USB/DVD download tool and create it afterwards. For me that is easier than having flash devices lying around (I loose those anyway
Last but not least, remember that you can still load drivers when you are booted on the recovery media. But that would mean or the network works (to connect to a file server or something) or the USB driver works to connect to a removable media...)
