So yes, the domain is aged, and technology related is also quite aged. Plus it is in plural, dialup com would be much better.
It seems nice though. I am not exactly sure here - it could serve also as nice brandable..I would say mid XXX - 2,5k for right end user, but because we speak about keyword which is not trending now (it was maybe trending around years 1995 - 2000), the probability of resale will reflect that downward trending pattern too.
Completely agree with lolwarrior. I honestly don't even know anybody still on dial-up connections. Catering to a very small market. But I guess anything could happen.
