Hey guys, I'm a total noob to both this forum and audio in general and I'm looking to replace my computer speaker system. Right now I have some cheap logitech x-640 and I'd like to replace them with something good but decent.

Fry's has a pretty good deal for r150s: http://shop3.outpost.com/product/496...H:MAIN_RSLT_PG
or r50s: http://shop3.outpost.com/product/400...H:MAIN_RSLT_PG

So the r150s would be 50$ total and the r50s would be 100$ total. I need a receiver to be able to hook it up to my computer, right? I'd like to keep the grand total at or under 250$ so whats a good receiver for 100-200$? I don't need anything fancy or with a lot of features, basically it'll be under my desk and just used to hook up the speakers to my computer. The ability to upgrade to 5.1 without buying a new receiver would be a bonus because I might do that in the future.

Any suggestions? And I understand that 250$ is probably a joke to all you audiophiles, but I'm sure whatever I end up getting will be infinitely better than the 50$ computer speakers I have now.
