Looking for a relatively good case. sky???

Hello all:

I'm trying to look for a new case for alto sax. I have a yamaha 62II and probably eventually will get a selmer paris horn, so a case that will fit both of those.

I found a case on amazon that looks like what I want, but also seems questionable because the price is very good and it is a brand I've never heard of before.

It's a sky case, and it says lightweight, which causes some alarm, but I was wondering if anyone had any opinion or experience with these cases

Thats a link to it on amazon, so you all can see it. I saw a protec case very similar to it a little while ago, but I can't seem to find it now. I would like a case that has backpack straps, an outside pouch for storage and able to protect the saxophone. I don't think I'll be doing any traveling by air anytime soon, so I won't need a case to survive that much, but I am in college and the saxophone is always moving around in a bulidng.

Any comments or recommendations?

Thank you for the help
