Usually use homebrew rig, built for 30 meters. Rx is a direct conversion phasing rig designed by Rick Campbell, KK7B, and modified by me to work on 30M. Tx and VFO that drives both the Rx and Tx is my own concoction. The keyer is an AccuKeyer, from an ancient Qst article thats been modified to prevent a few anomalies the original design had. So that now, the on air mistakes are mostly due to my own incompetence. The amp I use for this band is a homebrewed motorola design that uses a pair of MRF 421's.
My favorite way to operate is to go camping and use a full size dipole hung in pine trees at about 100 feet in the Chattahoochee National forest about 75 miles north of my QTH. I get them at that altitude using a spud gud I built from a QST article. When operating from the home QTH the antenna is a hamstick dipole (30M) at about 20 or 30 feet hung on an MFJ fibre glass pole stuck out the back door. Seems to work with 200watts about as well as 9 watts at 100 feet in the forest ! I've added an MFJ power supply tweaked up the voltage to get 200 W on 30 M.
Other rigs. Alinco DX 70 and Kenwood TS-820S. Use Alinco mobile with an assortment of single band hamstick antennas, or camping with 80 m dipole and 450 ohm feedline w tuner. TS 820 mostly gathers dust these days. It really sux the juice out of a battery.
Recently bought a Honda 1KW generator. Nice 'n quiet. Runs forever on a fart. Should have done that a long time ago. Beats toting 2 X115 amphour batts to the forest ! I now get 200W out instead of 160W and get to operate the TS 820 again. When I operate 30 meters, using the homebrew rig, I can hear the CW modulate the engine noise !
