The CTX is the best performing machine I have used to date. I prefer it over the T2, Omega 8000, White's V3i, Deus and the E-Trac. But, I am talking performance only and land use only. The balance is perfect, but the 5lb weight is a bit much for my back and elbow after around 3 or 4 hours (I feel it the next day, unless I hunt 6 hours or so - then I feel it then). Now, perhaps this is more me, though I am in very good shape but had an old back issue. I wish it was less bulky and broke down into 3 pieces - like most detectors. I can see how this is a dream machine for many detectorists that don't mind the weight, price, etc.
I do think Minelab dropped the ball by not making a light machine and making it more reasonable in price. It seems the weight is there because of the waterproofing design. Now, as many other posters have said, they don't love it in the water, though it is very good there to a few others. But, it seems most people are using it as an E-Trac replacement. I agree, it is worth around 1800 bucks or so. It is the best I have used performance wise, no doubt there. But, if you put an aftermarket coil on a mid priced detector, the performance will be close - as MANY have found out.
For starters, had Minelab done the following they really would have shocked the market:
Put the CTX in a Deus or light Teknetics like package - LIGHT - Many detectorists are older folks, which is why the Deus struck a cord with many. 5lbs is 5lbs, even with great balance (for many, NOT all).
Keep the price at 1800 or less
Just water resistant, not water proof (if this is contributing to the price)
Lose the GPS - Great for some, but most don't seem to be using it.
Lose the chips in the coil or at least make aftermarket coils from other manufacturers available. The coils now are VERY expensive.
Brighten up the screen and add some contrast controls. (The V3i has a better screen and gets good battery efficiency without Lion $$$ batteries, so something is up here.)
Again, I really like the performance but I am eagerly awaiting what Fisher has in store for us later this year, if rumors are true, and I know they are.

Till then, I will probably sell my CTX and pick up an X-Terra - not expecting it to be as good but I'll put an aftermarket coil on it and get very good performance. I just love the Minelab sounds...
