Thinking about getting a Teslong. Primary reason is to inspect chamber to make sure a carbon ring is not forming. Any other real benefit? Don't want to go down the rabbit hole of seeing things that were always there but I did not know about and thus did not bother me.
Also, a lot of models, which one will do the job w/o overspending.
