Thrustmaster sells the new TWCS throtle seperately as well, it's the only throttle out right now that I know of that has the same x45 style rocker for the rudder axis. It's very similar to the old Saitek in terms of how it feels when you move it. I got mine for under $100 CDN, I've seen them for 75 USD. It's pretty good quality, about the same as the CH Throttle IMO. It's wider than the CH throttle by a fair bit too, very well planted.
There is another option, the combo TM Hotas, it's lower end, but still really, really good, the stick twists, and the throttle also has a rudder bar, which TM refers to as its "dual rudder" system. I haven't tried this Hotas out as it's a little on the cheap side for me to add to the collection of them.
Just my opinion, but getting a good CH Combat with the TM TWCS throttle should run you under $175, and give you excellent controls for the $. If you want to save a bit, maybe try the T1600 Hall sensor TM stick with the TM throttle, again, haven't tried it, but heard a lot of good things here about the T1600 in terms of bang/$.
