I have the HTX-202 2 Meter HT and HTX-212 2 Meter Mobile rig. Although ancient, they still work well. The HTX-212, however is prone to severe overloading in strong signal areas where there are many signals in the band. The HTX-202 was a "brick", but very reliable in my opinion. A friend has, and still uses, an HTX-404, which is a 70cm HT, similiar in appearance to the HTX-202.
