Ι finished the “Stainless Steel Rat” and “The Stainless Steel Rat’s Revenge”, but I had to draw a line at the “Stainless Steel Rat Saves the World”… 
The books are “ok” for what they are I guess, but whatever happens in them is just so unlikely that I just cannot keep reading. I’ll just mention a mostly “spoiler free” example:
The first book begins with setting the premise of the main character who is a con-artist who is supposedly smart and charismatic who uses his mind and doesn’t kill people and has never run an “action type” theft or violently robbed a bank or whatever.
Fine, that’s cool, seems like the kind of fellow that might have inspired the creation of Pratchett’s “Moist von Lipwig” character. Alas, the author proceeds to abandon that premise immediately. Fast forward a few pages and the main character is robbing a bank. Which would have been fine, if the plan made any sense and if he didn’t proceed to rob a bank in the beggining of each other three books. 
Page 3 the character explains that a good con-man needs to be emotionally detatched from his con and if (or to be more exact, “when”) it fails, the conman should leave the con immediately and not get into the temptation of “salvaging” or “overstaying”.
There is even a limerick:
“Turn your back and walk away -
and live to graft another day”
AMAZING! That sounds like the kind of crafty fellow I’d like to read.
Alas the main character proceeds to become totally and inexplicably obsessed with his next graft/con/mission and goes to insane lengths and risking his life for, phenomenically not good reason other than “bruised ego”.
Unfortunately these books seems to be another case of what I mentioned earlier about D&D characters and not being able to roleplay an “17/18 Intelligence, 17/18 charisma” character because the player/author has no clue how those people could be like…
If you enjoy break-neck action then the books are ok.
If you have even the faintest idea of how any of that works then you might suffer from “suspension of disbelief” every page…
For example the way the main character goes in the “main town” in the second book without a plan, manages to wing it, messes it up totally and goes in and out of that military camp, was excruciating to read for me since I have been posted as a guard in military camps and had been an army officer for a while. None of it checks out. 
Next, I am going for Ian M. Banks’ “Culture Series” and its first book “Consider Phlebas”… I do not remember who suggested those books or where I heard of them, but considering that “phleva” means vein in Greek, the title was always a bit funny to me, but people say that this is a solid series, so I’ll give it a shot (no pun intended
).
