If it is intended for HF, I would consider the indian uBitx or using the (tr)usdx you have already (and likely more power efficient). The price reflects the fact there are not too many alternatives for a rig that works from HF to UHF with a reasonable power consumption. You might also wait for the new one. I think that they are developing a new QRP based on the 710 architecture. Look at the evolution: they started from the 101, then the 10, then the 710. A QRP must be the next!
