I've been ALL OVER that part work since they started testing it in the UK last year. They are trying to figure out a way to bring the subscriptions to the US and if they do, I'm getting one. I want them ALL! I've always dreamed of a really robust line like that, and I love the size of them.
Yeah I like the size of the individual ships, but they're all way out of scale to one another.
If you want a robust line of ships all in scale with one another, the only way to go is model kit.
You can find the Enterprise in A, Refit A, B, C, D, and E from AMT/Round Two in their Cadet series 1:2500 scale. Round Two also makes the Reliant, TOS Romulan BOP, TOS Klingon D-7, and Movie Klingon D-7 in this scale.
There's a Defiant out there by Round Two in 1:2500 scale, but it comes with the Deep Space Nine space station in 1:3300 scale.
There's also F-Toys, they made the NX Enterprise, Defiant, TOS Enterprise and refit in 1:2500. Furuta only made the Defiant in this scale.
For any of the others in 1:2500 you'd have to go the Garage Kit route. You can find almost any ship (Including the Abramsverse ships) in this scale that way for very good quality, though many of the ships are sold out at the moment and hard to find.
Speaking of model kits, this year AMT/Round Two is re-releasing the NX-01 Enterprise in 1:350, but even more interesting is that AMT/Round Two will be releasing the NX-01 Refit in 1:1000 later in 2013!
I haven't built a Star Trek model in a little over a decade, but seeing this has rekindled that spark. I'm going to get some of the 1:2500 Cadet kits and start warming up for the Refit NX-01.
