I have full CH USB, the TM Warthog, and Saitek Combat peds. I think the Saitek Combat pedals are the best bang for the buck, I find them more comfortable than the CH pedals, as they are wider apart, and have a sturdier construction by a small margin. As for sticks and throttles, I've tried my bro in laws Saitek X52Pro, and it's decent enough, better than my old X45, but I still think that the CH Fighter or Combat stick more precise and smooth, and the best choice for WW2/AH2 where aim is critical.
For other sims like Jet sims from DCS, I use the Warthog, as being spot on with gunnery isn't nearly as important.
I would avoid the Saitek X65 for WW2 sims myself. I know some noted sticks in the game like S-Hawk have figured out how to make them work, but they are counter intuitive for precise aiming IMO and take a lot of effort and time to get used to, as it's a stick that works like the real life F16 and F22, by sensing pressure and not moving more than a couple milometers if at all. Plus it's very expensive and prone to problems from the tech support boards I've read. Every manufacturer you can read horror stories about, I know that the TM Warthog has a bad rep for certain parts failing too. That said, CH seems to have the best overall rep for longetivity and sturdiness. I've had 2 full sets of CH USB gear in the last 11 or 12 years, and one set came as a review freebie back when I did some reviews for a website on hardware, and all three units still work great on a friends system all these years later.
So, since you said $ isn't an issue, but value is, going with the CH stuff IMO is the best route to take. You can even get by with just picking up each part of the stick/rudder/throttle a unit at a time if you can't afford the 300+ it'll cost, but if that isn't an big deal to you, I'd just get the CH stick and throttle, and buy the Saitek Combat pedals to go with them.
