I want to build a light one.

What is the cost of the Kits ?
Where are the available from ? Any links please to good flying and affordable kits ...

What about the plans ? Please give me links for plans also ...
I hope its not very difficult to build from plans .... i hope its more or less like R/C building.

What do you suggest ? It's my first project .... I've done a lot of r/c ..all kinds of building experience for R/C ... but have not a single job for full scales ... What you think someone like me should do ?
