I upgraded from the original T300RS when it shipped with only two pedals as standard. After multiple issues with it ranging from non-calibrating to clunks, crunches, squeaks, and a warranty exchanged the entire system, enough was enough.
Purchased the Fanatec CSL Elite during a black Friday sale (you may want to consider waiting until Thanksgiving to take advantage of the Black Friday sales to help with your budget). The setup I ordered was the CSL Elite with V3i pedals, but at the time the pedals were on back order around a 5 month wait. So used the Fanatec base two pedal (non-LC) for the interim. Was really impressed with the two pedal unit, solid build quality, good feel and even had a little foam bumper behind the brake pedal. Probably about on par with the T3PA pedals although I've never used the T3PAs.
The overall build quality and adjustability of the Fanatec system is far better than the T300RS and you will not be disappointed.
Bottom line, if your Thrustmaster is working reliably now, and budget is an issue, start researching but wait until the next Black Friday sale and get what you want for a much better price.
You've sparked my curiosity, can you give more details on what you mean?
