What you're essentially doing here is asking us to make a judgment on a product simply based on the name brand attached to the product, which is a lot like asking us to tell you a good car to buy just by telling you "Get a Honda" or "Get a BMW". While some companies do make bargain RAM, and others, high-performance, it is a tendency, never a rule.
Firstly, decide what type of frequency and DIMM your RAM uses. You can decide this by going to the website of your computer manufacturer and looking up the model number of your computer. Oftentimes, the manufacturer will offer RAM that is guaranteed to match your computer, but it is generally not the best you can get, nor is any 2GB package you get for that amount of money going to be.
Getting 2GB of any RAM for under 120$ is quite difficult, really. Judging by your posts, you haven't really taken into consideration other things in your computer that may be hindering your performance - but we'll stick with RAM.
Once you've determined the information I asked you for, post it here and I'll help guide you through getting some new RAM.
