Tan at home is sweet
A few years ago I purchased a tanning bed from a tanning
salon that was going out of business. You could buy direct but
you will obvious pay more.
If you do not plan on purchasing a commercial grade machine, then I would say that the cheaper machines are not worth it since it fails to fully cover the whole body due to having less bulbs to surround the body. You will definitely get tanned
from the home machines but will have to rotate many times
to tan the whole body which will take 2 to 3 times longer to
tan.
The experience that I have had with the bulbs was that they are rated for 500-1000 hours which could last 2 years if you use it
every day for one hour.
In closing, If you could afford it I would go for it. It is great to
have and very convienient.
