Which is cheaper depends on the deal you find. Just go to some sites that sell them and look at the prices.
The above posts are accurate with or without mods. Oblivion for combat and graphics, Morrowind for depth and unique setting/feel. I would only add two things. 1) If you're hoping to get an extremely long amount of time out of your game, Morrowind has a lot more good quest mods for you to play through. 2) Morrowind's dialog is text-only except for short greetings when you walk past people, and with none of those Radiant AI conversations whatsoever. (In fact there is no Radiant AI. The NPCs are very static.) So if you hate games that make you read, Morrowind is not for you.
"Easier to mod" could mean to add mods to, or to make mods for. Oblivion is easier to add mods to, because it freaks out a less about load order, adding/removing mods, etc.. It's also less prone to get crashy when heavily modded, at least for me. Morrowind needs more mods in my opinion because it's age makes it uglier and clunkier, and more mods means a more complicated experience making them all work. However, Morrowind is better if you're looking for a platform for your own mods. The assets are simpler and so easier to make your own to match, and you won't have to worry about voice acting.
You can download mods on a different PC and copy them onto the one you're playing on. Mods aren't an automatic process like buying DLC on your PS3 probably is. You actually download a zip/rar/7z and then extract its contents to the right place in your Morrowind/Oblivion install. But be aware that mods can get really big, so you'll need a fair amount of time on a good connection to collect the ones you want. Could be an issue if your only Internet is the library or a relative with dial-up.
