I took the plunge and bought a sub-adult mali uro at a herp show this weekend. I already have a young adult mali female, and the vendor was pretty sure the one I purchased is a male. It was his last mali and he claimed he had it for about six months and it was doing well. It's a bit thin looking, but luckily it fed after I set it up in its new cage yesterday. It's inquisitive and not nervous, and fed very well again today on some fresh greens after it warmed up under the UVB/heat bulb this morning. I am keeping my fingers crossed he does well and will make a mate for my female in another year or two!!
