Don't worry about things being rough and ready... My first LEM involved me trying to get something worthwhile from a cheap FleaBay purchase... The guys there helped me get it working and aligned into something useful... then I killed it (and my shiny new FB3 plus the usb ports on my laptop! ) trying to squeeze it into an old Parc an case I found in my scrap metal pile!
Rough and ready is how the best things start
