Stateside, they are standard issue, and most new or even 50-year-old construction has provision for a dryer hook up. In California, electricity is 15 cents/KwHr, on the high end of prices for the USA, and it has always been more economical to use a natural gas dryer. While the machine may cost $40-60 more than its electric version, the cost gap is quickly recouped.
Most condenser type dryers are European in make and size (24inch/60 cm instead of 27 inch/70 cm), for use where there is no venting: converted closets, under kitchen counters. That said, most mid-century or later houses and condominiums have a laundry area with hook ups and venting.
My current dryer is a Frigidaire/Electrolux gas model, which stacks on top of its matching washer. Although I have space to place them side by side, I choose to stack so that I can use the freed space for something else (a table for folding and storing clothes). The two most important features of my dryer to me are:
1. Moisture sensor. My former dryer was mid-range but did NOT have this feature, and sometimes shut off before clothes were fully dry, or it would cook the clothes long past the point where they were dry
2. Permanent press cycle: starts out warm, releases wrinkles, then cools down to lock in "straightness". By cycle end, clothes are room temperature.
Most of my work clothing is office casual: khaki trousers and collared shirts (no ties), all 100% cotton with no-wrinkle finish, and nearly all of them from LL Bean (
www.llbean.com). If hung up promptly, they look as if someone slaved over an ironing board, but the system only works with a moisture sensor and a true perm press cycle. Next to my machines I have a "laundry center", a set of steel shelving with a rod to hang the clothes, plus three sorting bags. Similar to the device in the photo, except mine has a shelf above the hanging bar allowing storage of lightweight items. So I am well equipped to hang clothes after drying. I need a device on wheels, because the tank water heater is tucked in the corner next to the washer/dryer stack, and if service is required, I have to be able to move the laundry organiser without a lot of fuss.
PS: if you buy a dryer with moisture sensor, and if you use dryer sheets, the waxy substance in them can coat the sensor and render it less effective. I tear the sheets into thirds, using only enough to prevent static cling, and clean the sensor with alcohol on a quarterly basis.
