Can anyone please tell me the difference between a silhouette cameo die cutting machine and a silhouette electronic cutting machine?

Would someone please tell me the best adhesive runner to buy.   I used to use Stamping Up and I really liked that one but its been ages since I scrapped.

Thanks Killarney_Rose, lots of info for me!  I do have the original cricut and the old sizzix.  Is the cricut still in the loop?  I know theres a larger one out now, is there a machine more popular than the cricut?  Thanks to all you kind ladies for all your information and tips.

I have not been scrapping for about six years now.  I would really appreciate some updated news.  Can anyone tell me about your favorite new and wonderful tool, template and or any thing just wonderful about scrapbooking!  Please PM me so I don't miss any thing!  Thanks!
