Topgazza,
never used a Scorpion type saw so cannot comment on that, but own and have used reciprocating saw many times.
I presume that Scorpion type saw with its deeper blades are more accurate than reciprocating saw (who blades seem to wave about a lot more). But I have made some fairly accurate cuts with reciprocating saw.
I found the Mac-Allister-Reciprocating-Saw (£55) to be great value and lasted me very well. The down side has been that the bolt holding on the 'shoe plate' sheared off so I had to fix this with a new 4mm bolt. The up side is that it is not too heavy, I like its long body length and it relative low vibration in my arms. I bought it as a cheap throw away item, but (for me at least) it has lasted 3 years of relatively hard work.
I have also used the Hitachi Reciprocating-Saw from
Screwfix (£130) which was nice as it is shorter in body length, but I found it produced much more tiring vibrations travelling into my arms.
Looking at the DeWatt saw that you showed, it looks great, but I think I have got used to the 'long thin' dimensions, rather than the gun shape. As a halfway cost did you consider the DeWalt DW304PK (£100)? Its head can be rotated in 90degree steps, but this might be a gimmick.

So my summary:
- The Mac-Allister was great for me needing a cheap, fast Reciprocating-Saw with low vibrations and variable speed. But I am sure it is not great for Trade use.
- Throw away the free blades you get and use good branded blades (such as Bosch blades from
Screwfix).
- These saws are heavy and I would worry about using a mailorder company as posting it back if it goes wrong would be very expensive.
