Hello 
Yes, I have three different cabinets. Example:
If you go on Amazon or eBay, you’ll see that the basic designs all look very similar even though there are a wide array of companies. It’s because the cabinets are nearly identical with minor branding tweaks among brands. They are all made in the same factory in China. So just get whichever happens to be the best deal. I paid between $150 - $250 for mine.
I keep it at 45% humidity. I keep a hygrometer inside to ensure the LED humidity level displayed is accurate.
