I have a couple of Gator cases that I bought to save some money compared to SKB. The Gators are OK, but they are not perfect. The handles and the "cut outs" for your hands are too small for many (most?) grown up men. I do not have very big hands, but it still get my hads squeezed hard when I lift one of these racks as soon as it has some kgs of equipment inside.
The other annoying thing is that the latches and hinges are placed in the opposite way, compared to most other gear I have seen. The movable parts are not on the lids, but on the case itself. This means that if you use the case for a bass amp, the case will vibrate and rattle if you but it on top of a speaker cab. The rattle is very audible if you play at lower SPL, like for jazz, folk or singer/songwriter style.
If you are on a budget, I recommend to look at Thomann's own brand of cases. I have one of those, too, and it is very similar to the SKB design, but not as high quality.
I'm using this to house a 4u rack power amp that is crazy heavy, and so far the weight has not caused any problems.
This case has also currently got 2 other rack cases on top of it, a 10U and an 8U and this has also caused no sagging or other problems.
The catches are decent quality and feel like they'll hold up to continued use, which can't be said for some of the cheaper rack cases.
Also important to note, the case comes a pack of rack bolts and plastic washers. There is nothing in the product listing either on Thomann or the Gator website to confirm this, so I wasn't sure prior to purchasing whether they would be included.
Being a US brand, Gator use an imperial size bolt which is a pain to source in Europe. Worth bearing in mind if you think you'll need replacements later on.
The supplied plastic washers are poor quality, but decent nylon washers can ce bought for pennies.
Its worth considering using "Hum frees" as a substitute.
