I also purchased mine from JTSELEC via E-Bay. Very satisfied with it. The 60 watt option makes it very nice for mobiles, etc. I would also look for the high stability reference oscillator. Mine has it and it's nice for improved accuracy. It may be something that they all have, I'm not sure on that. It's not the most portable box, but it has a lot of nice features. I would think you should be able to pick one up for under a grand.
