I think it's best not to consider lab stones as a cheap alternative. They are cheap-er than their mined counterparts, but not cheap. I chose a lab Asscher because I couldn't find any mined ones that I liked within my budget, and if I did like them, they were too small.
I'm not sure what your budget is but unless you're chasing a VVS1 DEF stone, you'll find some crazy bargains in the lab world.
Holy heck! You got a gorgeous asscher! Can you tell me the specs?
Thanks! It's a 1.62ct VS1 L colour CVD lab stone. I was trying to avoid a lower colour this time but she was just perfect in ratio (basically 1:1) and her steps were lovely so I went for it. She's warm but at times fairly close to J/K.
