I have all three of these burners, and I think I like the 1620 and 1640 the best.
My first 1655 was awesom, but that broke, and my 2nd and 3rd 1655 does not seem to impress me, like my 1st one did.
I do not use LiteScribe, so that feature is useless to me.
Is there any reason to think that the 1655 is better, just because it is newer?
Thanks for any input you may have!
