I have one of these that I used for work. It does the job, but it takes forever to dub. It's not fast. Also, it is confusing as heck to do if you don't read the manual, and even then, it's still confusing.
I'd suggest going to a local shop and have them do it. The time you spend trying to do it yourself, it's worth it to pay somebody else to do it professionally and have it done fast. Of course, if there's a pool person local to you that has this capability and will do it, that would be ideal too.
