It's nice that you bring up the SPE 1K, since it demonstrates very nicely the loss you can suffer with a built-in tuner.
The ARRL review (http://www.arrl.org/files/file/protected/Group/Members/ProductReview/pdf/pr0909.pdf) said that there was 100-200W loss in the internal tuner, and presumably this is into a matched load in the laboratory. With a mismatched load the losses are generally going to be even higher. With solid-state power costing upwards of $3-$4/watt these days ($3.20 in this case), why anyone wants to leave $500-600 worth in the box is beyond me. But then I could never get my arms around the whole mismatched antenna/ladderline/balun/tuner thing in the first place.
