Serger suggestions?

Just a short and sweet post.  I decided posting something personal or just something short was better than posting nothing at all!

I'm out to go serger shopping this weekend....anyone have any suggestions?  I have a machine/brand in mind, but I'm curious what you've had experience with and what issues you've had.

Here's what I'm looking at:

The Viking/Husquvarna Huskylock s21

I like the big workspace, the mesh scrap bag, and the space between the needle and the inside of the machine.  I've read a million blogs, reviews, and websites, and it seems this is where I'm headed.  Anyone have any experience?

While we are on the subject of suggestions, anyone have tips for blogging with Blogger on an Ipad?  I have an app I use, but it's not perfect.  It's taken a lot of tweaking just to figure out how to place pictures in it correctly, among other things. 

I'm new to the iPad, but I have to say, it will be great to have on my sewing table this weekend!  Way easier than lugging around my laptop, it's hard not to treat it like a book, forgetting it needs charging and that you can't toss it on the bed like a book. Not that you can't, it's just not advisable. 

One last thing - I have my PT appt at 5 today.  I have to tell her the refined exercises she gave my Monday still hurt too much to do, which is going to send me right back to the Orthopedist.  I figured that would happen, but not 3 appointments in.  Quick turnaround.  Keep me in mind if you think about it today - and I'll keep you posted on the doctor. :)
