Memorex 48x12x48 Internal CD-RW Drive Model 32023248 is it any good? I don't need it to store a lot of stuff just to backup a few things. Also does anyone know if it will just plug into my Compaq Model 5716 computer? I've never installed anything in a computer before so does it plug right in without having to buy any other cables & etc. I figure for $15.00 (with rebates) & that's about all I want to spend but wanted some advice before I bought it. My local store is already out of it but thay said more will be in this thursday. Thanks for any help you can give me.
