It looks like my easiest route is to simply buy a bootable USB or DVD, on Ebay. The CD/DVD's are cheaper but then they would tie up my DVD, so I'll go with the USB.
One thing to watch out for, making sure that the versions installed aren't old ones. LTS versions such as 14.04 are fine, anything below that, including 12.04, isn't. Unless one has a really older computer.
Some of these Flash drives, depending on size, may have several distros in stalled, you pick the one wanted at boot.
The reason why I bring this up is because have seen eBay Linux sellers offer versions that are years old. Until a couple of years ago, even the long abandoned 'Freespire' Linux OS (I bet many on this forum hasn't heard of that one) was still being distributed in a package of 'top' Linux distros. The seller should have stated 'classic', abandoned', 'obsolete' or 'antique' in the description, rather than outright deceive buyers. In fact, several vendors were still selling Freespire, unfortunately I bought one of these back in 2010 or so, it was dead 2-3 years before then, so selling in 2013 is outright thievery. Their last release was back in 2007, the same year that I began taking more of an enthusiast approach to computers, a desire to learn rather than just be another user.
And one like this at $114.94 is well overpriced.
For that price, one can purchase a dozen 8GiB sized Flash drives & make their own (what I do, but prefer a 16-32GiB model for full install). The above seller isn't even providing a Flash drive with a Full install, rather using a 4096MiB persistence file.
