The paid version of Betsi is $72 for the year, but they have a special for $48 right now through some blog, I am sure you could Google it. The free version of Betsi does all the same things as craftopolis, but I feel like it has a more user friendly layout. The paid version does everything the free version does but with more added features like being able to change/update tags, which is really the biggest reason I went with the paid version. It also does images, shipping, .... pretty much every field etsy has.
I used their replace feature today. I put the old link I had for a category, then told it the new link for the changes I made and it made the changes to all the listings with those categories with literally the click of a button. Love it!! The paid version has a free trial, so you could try it before you pay as well. I did that and when the trial was up I couldn't let it go!! :)
HTH!
