IMNSHO, yes. They really do offer the best bang-for-the-buck in the under-$10k analog board market. They aren't that common, because not a lot of home recordists have 6 or 7 grand to drop on their boards- but if you need (or just want!) the features they offer, they are the only way to get 'em for less than 10 grand (or buying a used large-format board through a broker).
Pros: they are a semi-large-format board: the channel strips are larger, controls are larger and easier to see and handle, 100mm faders allow much more comfortable operation. However, they are still in a somewhat portable frame- the Ghost bridges the gap between large (pro studio) and small (Mackieish) formats. If you bought a used studio board, you'd get one whompin' piece of gear that would be hard to fit in a normal home environment- not so with the Ghost. It has very usable pres, very usable EQ, and its summing buses are quite quiet compared to most entry-level boards. Mine easily exceeds its specs for equivalent input noise: it is 6-8dB quieter in every aspect than the Alesis Studio 32 it replaced (not to mention being big enough that I don't need to operate the controls with a pair of needlenose pliers...) The signal routing flexibility is top-notch, and allows a lot of very sophisticated routing of submixes and the like without requiring repatching. There are enough busses for anythig I need, and that's a wonderful chanes from the Alesis... It's an inline board, so you have proper tape playback support with A and B mixes and channel/tape path swapping. The tape return gain trims ares separate from the channel gain settings: a very nice touch. Polarity invert per channel, which is seldom seen on an inexpensive board. You have a proper foldback mix and talkback facilities, you have built-in abilities to handle several monitor setups for A/B- all in all, it's a lot of board.
Cons- there are few, but there are some. The mic pres get a little noisy when run above about 50dB of gain (compared to their lower settings, even up there they are still quieter than my Alesis was run at the equivalent gain)- there's an abrupt increase in noise up there. So use external pres for your ribbons. It is a large unit, so even as reasonably-sized as it is, there'll be a lot of home studios it just wouldn't fit into. Its behavior when run into clipping is rather obnoxious- it really sounds _extremely_ unpleasant in the monitors (the solution, of course, is simply not to do that- you do not _need_ to be outputting +30dBm into your recorder, now...). And many of the outputs are impedance-balanced rather that true differential- a small thing, and a significant cost savings, and inaudible, but since I'm a circuit designer in my real life, I'm allowed to ding it on that topic...(;-)
The board sounds _excellent_ compared to any budget board: you do get an improvement in sound for your investment. I cut my teeth on large-format boards, and when I got back into recording I wanted that feel and working style again. The Ghost feels like a proper large-format board, and acommodates that working style very well. It's a lot of board, and you can bet your butt I'm keeping mine. However, it's also a lot of money, so it'll provide different value for each person. Only you can make that call.
Ideally, you'd go lay hands on one _somewhere_: even finding a little commercial studio somewhere that has one, and booking an hour of their slack time to just work with it and talk to their resident engineer about it. But if you throw caution to the winds and buy one sight unseen, you will not be getting a turkey...
