I've had three...two that I from Wal-Mart one from Radio Shack. None of the three have given my car fuses problems, but one of the three did have heat problems (got too hot) and eventually stopped working. The one that seems to run coolest for me and seems very reliable is called a PowerLine which I bought at WalMart. This model has two receptacles and has 200W rating (continuous) and 400W (peak). It also has a 5V USB connection. I think I paid right around $30.
From what I can tell, the key to these things operating best is that they can generate some heat, so a good internal fan inside the unit seems essential along with adequate air flow/ventilation. So when you're using it in your car, make sure it's not sitting in the direct sunlight or covered by a bunch of stuff laying on the floor of your car, which of course would keep the air from flowing freely.
BTW, I'd venture to guess that the people that are bitching about these things blowing out their car fuses are barking up the wrong tree. It's probably not the inverter causing the problems, but the operator putting too much load on the inverter by plugging in...say...hair dryers at the campground (inherently high current draw), TVs, radio's, etc. and expecting their dryers to work just like they do at home. Be smart...these things are operating off a 12v car battery...use it with minimal loads connected at once...or only connect what you NEED to connect at any given time and you shouldn't have problems. You can't expect to use these things with a christmas tree of cords coming off of them without something blowing.
It's not a bad idea to get to know which circuit in your car your cigarette lighter is on and then buy some spare fuses to bring along with you in case you do blow one out along the way. After all, that's what a fuse is supposed to do...provide protection so that your electronics don't fry before the fuse does. Frankly, I'd be pretty happy to know that the fuses are blowing first (instead of bitching that the inverter is causing blown fuses). Fuses are like 25cents each and can be purchased at Wal Mart or Radio Shack in packages of I think 4 or 6.
Another basic 'rule of thumb' that I use is that whenever the inverter goes into the car, the jumper cables go too. If you use an inverter very much, it's only a matter of time...you _WILL_ drain your battery too far at some point and need a jump...even if the inverter is supposed to cut off on low voltage. In my experience, by the time that happens, my battery is too low to start the car.
