I don't think anyone is responding because it's near impossible to appraise a .TO domain...Especially a random 3 letter .TO domain.There really haven't been any serious sales of .TO domains,and they're quite expensive to register ($100 a year) making them unattractive to both speculators and end users.
The fact that with the sub-domain "del" makes it read as an Italian word doesn't add value,as there's thousands of available domains to make using that approach.
Obviously "development" would help..but then we'd be appraising the site,and not the domain.Unfortunately is has no value IMO.
