Relatively(?) inexpensive full auto?

I am thinking in a year or so(after the SCAR light, thats what I'm saving up for now) of getting a full auto. I know I will need tax stamp, and I know that will take a while, so mods, not asking for anything illegal. I like the old stuff, so I thought maybe a Sten, but just want to waste a little time right now and I like to here what you have to say.

Thanks
