It depends, what model specifically do you have?
I got an 'Omega View 45D' as my first 4x5, and by first I mean less than a year ago. And I think I paid more in shipping than for the actual camera, still not much for either though.
To echo what Tom said, the standard blocks can be overtightened and can break, and once they're broken they're hard to glue. I noticed it after using it for a few weeks, but couldn't tell (let alone prove) whether it had come like that or if I'd done it so I couldn't return it.
I've seen someone selling blocks on fleabay for only $10, but it's $60 shipping from the US so not really worth it.
Other than that, it's not a bad camera. Simple lock/release tilt/shift/swing/rise etc, only gearing is fine-focus. Bellows are allegedly non-interchangeable, but there's only 9 screws to undo and a bit of glue to break, and you can interchange with other Toyo/Omega bellows (I had a 45G bag-bellows on mine until I got my 45G). Rails are also non-extendable but easily swapped to extendable ones.
Flash forward to a month ago, and I picked up Polyglot's old Toyo View 45G.
Metal standard clamps, no more cracking. Geared rise and shift, plus fine-focus, simple release tilt/swing. Only 1 fault I've found with it so far is that the gear-rail for the geared-shift is loose, I'll attack it with a screwdriver one day.
In short, it's a much better camera, more solid, but man it's heavier because of it. So much so that I'm almost considering keeping the 45D, at least until I get my travelwide, then I'll on-sell it.
I'm not sure if Omega View ever rebadged the Toyo View 45E/G/Gii/GX/C/CX, or if they just stuck with the 45D. Certainly the 45D was the baby, the prototype, whatever you want to call it, and they certainly fixed a lot of its problems in the 45E and later models. But it's still not a bad camera for learning, they're certainly cheap, and fine as long as you know its limitations (just don't overtighten those standard-clamps).
