Genuinely, thank you everybody for the advice and help in this thread and on the forum. I've now purchased the White's SPP PI machine that was being sold on the classifieds here. Shipping on the 2200D was going to push it out of my price range, and I can't quite put my finger on it, but through my research the White's machines just kept drawing me back in. I think with the right coil and practice it will be a very capable little unit. Seems like it will pack small for hiking as well.
Now I just have to wait for it to arrive and figure out where to start!
Thanks again everybody.
