This really is a great workstation, and I love that it doubles as a light table, I just use a small 8" florescent under cabinet light and set it right in the catch-all drawer and it works great for me.  For sturdiness, just make sure you really tighten all of the screws and bolts, mine sits on a hard floor and is quite sturdy.  My only real complaint would be the process of putting it together.  If you don't have small hands or aren't nimble, you will have a difficult time with some of the bolts...even if you do, you will have a difficult time, so be prepared for it to take at least 2 hours to put together.  Also be careful to have the middle bar flipped the right way....I ended up having to change it twice!  All in all I am pleased with my purchase.

Pros: Great Value, Nice Size, Good Organization Options
Cons: Somewhat Difficult to Assemble
