The Maya interface is very easy to use, comared to free software like Blender. The cost of the latest version (8.5) is $1999, so make sure you have enough memory and dual core computer for maximum performance.
Is there any other cheap and easy software which works like Maya ? .
blender is totally free and has some features that are even better than maya. Sculpt mode for example, and because it's open source, some of the best uv unwrapping algos on the market. There's so much it is hard to do it justice.
