I purchased one on Ebay for $30.00 including shipping. It is an aluminum case, with 4 compartments that pull out (2 pull out to the left, 2 pull out to the right) they come with dividers the you can place where you want, so you can keep everything tiddy. And also a very large compartment under those 4 pull out ones. 1 of the P/O compartments can hold 12 MAC E/S in thier boxes ( 2 rows of 6). So I have 24 E/S in the 2 top most compartmens. The the middle compartments can hold your burshes, pencils, or what have you. I recommend a train case if you like to keep your M/U neat and tiddy. Plus this one came with a shoulder strap for when you are on the go, and latches that lock w/ a key. Whew ... Hope that helps!
