We are on the same page here. I agree completely. But not all people think the way you do. Then even some that might think that way are not able to just drop the money for whatever they want.
Plenty if not most people get into this hobby without doing all their homework so they are behind the curve from the start. It takes them some time to correct the issues and get the right stuff as not everyone can but the best option. I sure wish they could as I hate seeing anybody use a cheap tstat. I bought one early on as a temporary setup as recommended by so many here and it quickly failed before it hit two months of use. It failed on and was running up the juice when I found it. From that day on I stopped suggesting and el cheapo tstats. I can still agree they are better than nothing but I would rather a person use a lamp with a dimmer while the save up for better equipment.
