Little Hornet with a couple Program Carriers and the Overclocker Positive Quality is all you'll ever need for a Sleaze Decker. Matrix Actions are Complex Actions, you'll only be using one stat for your limit at a time. Focus on Sleaze actions and leave your highest number in Sleaze, leave the 2nd highest in Firewall. On those occasions you need to be doing Data Processing or Attack move the Sleaze over for that action, move it back when you're done with that one action. And really the only Attack action you'll be doing is breaking file encryption, toss a point of Edge at it if you really need to keep your Sleaze up. Or grab Perfect Time and swap at the start of your action, then back when you're done.
Seriously, 200k for a deck isn't by any stretch required.
