No matter who you use, I highly recommend anyone with VHS home movies get this done. The tapes definitely degrade over time, and having them digitized and put on disc makes them way more portable and durable.
I had boxes of tapes from when my girls were little, and if I hadn't had them put on DVD they would have eventually been unwatchable. I'm sure the rest of the family would breathe a sigh of relief they didn't have to sit through my infamous Thanksgiving dinner video fests, but I don't care. I love those movies.
Even though the service really wasn't that expensive, I still consider it one of the best purchases I have ever made.
