Been looking at the $49.95 Premiere refurb sale going on right now and have an upgrade itch that I'm considering scratching. I have an S3 (on lifetime) that I use in my primary viewing area and an HD in my secondary viewing area that gets very rarely used (6.95 monthly--hacked due to Frontier FIOS and their crappy always on copy once flag). I'm mostly content with both but with the sale running today have thought about upgrading to the Premiere and it's UI (which i like but is deathly slow on the S3/HD--it IS faster on the premiere right?). So I've thought about buying a Premiere then trying to get lifetime on my HD and selling it. Also thought about just buying an XL4 and selling everything else as my HD is pretty rarely used (but it does get used). I guess I'm asking advice from those that have been in my position before--did you upgrade and never look back? Any regrets? Thanks in advance for the advice!
