Thank you all for your replies
I'm glad I'll be able to feed locusts instead of crickets... Ugh, disgusting creatures!
At the minute I just need to decide on an enclosure I think, got everything else lined up and ready to buy. I really don't mind retrofitting a screen enclosure to seal up the mesh / completely cover it in climbing plants if it means I get twice as much space as a glass enclosure for the same price. I'll have to do a bit more research!
I'll be glad once all of this is out of the way so I can actually start looking into where to get a Crested Gecko lol.
Thanks again. Maybe in future I'll have some pictures to share, providing my awesome DIY skills don't fail me...
