Seems you're pretty well catered for already, but people that are interested in a more budget friendly solution however are not and I'd bet that is the biggest group out there which is lost to Fanatec at the moment.
The only problem with that is even Fanatec's "budget" wheel base is a lot more expensive than any other budget wheels. The CSL range is in no man's land. Too expensive for people wanting a set up on a budget, and built too cheaply for those wanting higher-end stuff.
A CSL base here in Aus costs $100 more than a T300. The CSL provides slightly better FFB from all the reviews I've read/seen, but that price is a problem. The cheapest rim from Fanatec is the Formula Black, at $300, but what if I wanted a GT rim too? Well I could get the CSL wheel, assuming they'll release a PS4 version of that, but it's built about as well as a T150 rim, and still costs $150, so forget that. I'd have to get the next cheapest GT rim, the BMW one, which is $400.
So, if I wanted this wheel for my PS4, I'd be paying $500 for the base, $300 for a Formula rim, and $400 for a GT rim. I already have CSPs, but for people who don't, they'd be better off buying used V1s or V2s, as the V3s cost more than a PS4 at $500... If I wanted an H-pattern shifter, which I would, I'd also have to add to that the CS shifter at $330. So for that setup, the CSL base, two rims, and a shifter, I'd be paying a total of over $1500. Remember, that's without pedals, because I don't need new pedals.
The T300 costs $400, which comes with a GT rim ( you can choose either the RS or the Ferrari GTE for that price, depending what rim you prefer). Add to that $220 for the F1 rim, and $250 for the shifter. The only other thing I'd have to buy is a CPX adaptor to use my CSPs with the TM gear, which cost less than $100. That gives me a total of less than $1000.
Now, is the above CSL set up better than the T300 set up? Sure, of course it would be. A little better FFB, much better rims, and a better shifter. But is that worth an extra 50% over what the TM set up costs? I'm not so sure.
Now, I'm planning to get an XB1 at some stage, to play the Forza games, so it'd be wise to factor that into my next wheel purchase. I could buy a TX servo base for $330, which works fine with the rims and shifter I'd get with the T300. With the CSL, the base is PS4 compatible, so I'd need a regular CSL base, for another $500, plus XB1 compatible rims, since the two I listed above aren't XB1 compatible. Again, I wouldn't be remotely interested in the CSL rim, so I'd need to fork out a ridiculous $700 for an XB1 compatible Fanatec rim. That's $150 more than a new PS4 Pro, just for a rim...
That brings the totals up to $1300 for a TM set up which would work with both consoles, and a whopping $2700 for a Fanatec set up for both consoles. At that point, it definitely isn't worth it for me. $2000 is already beyond what I'm willing to spend on a toy wheel to play videogames with. For both consoles, the TM set up would cost less than half that of the Fanatec set up.
I specifically didn't factor reliability into it, because although TM doesn't have a great reliability record, neither does Fanatec.
