Well, let me put it to you this way...
Years ago, I loved a Microsoft Precision Pro... It was a great stick that served me well... But Microsoft stopped making it.
Years later, I loved my Saitek X-45... It was a great stick (not quite durable though), that served me well... But Saitek stopped making it.
Now, I have CH Fighterstick... It is a great stick, that's serving me well... And it doesn't look like CH will stop making it anytime soon.
Every single time that you transition from new equipment, it is a pain in the butt. Retraining muscle memory isn't the easiest thing to do. This isn't just in cases of going from, say, a Saitek to a CH, but even just from your familiar Saitek to a new Saitek. It won't have the same exact feel and you WILL need to re-teach yourself. You might get lucky and have a solid Saitek that lasts for years, but the odds are against you. Imagine what getting used to a new stick every 6-9 months will be like.
IF you have the money, and IF you KNOW you are going to be addicted to these games for years to come, invest in CH products. If not, get something else.
