The only expense required was a $5 connector between my stereo amplifier and PC sound card. Over the last couple of years I've converted a couple hundred audio cassettes and dozens of LPs to MP3s and WMAs, many of which were ultimately burned onto CDs.
A couple of people recommended USB turntables that automate the process and cost from $70 to more than $230. A couple of weeks ago, 'k_hettich' posted a question in CNET's How-To forum asking about converting vinyl LPs to CDs.
