Hi Jack

I think you should go down to your LHS and get yourself a SIG Kadet LT-40 kit and why you're there, pick one up for me and send it down here to Australia.   From what I've read, I think they are the best trainer.  I want to bget it in a kit so I can build it myself but I'm finding it really hard to get a hold of one here.  But I'm sure others will chime in.  I am as new to this hobby as you are!
