I like the name. It's very versatile, a factor which can either kill or help a dn be attractive to EU's. It's kind of in the limbo zone where you're not quite sure of an exact use, but there seem to be many uses waiting just beyond the horizon, just can't see them clearly.
I wouldn't think it's as valuable as the very common 'deselect', but I think it's more attractive for branding due to the 'positive' message - RE instead of DE.
I expect it would be a hard sell to convince someone/company with the initials RE that 'select' would be a great name to tag onto it (like real estate select), I feel the value here is in straight branding of the word. I'd appraise:
resellers = $150 - 250 range, add another C-note if they really like it. It's neat enough to want to have, but the use is so nebulous I doubt a reseller would want to take a chance with more $$ than this.
end user = $500 - 800?; I think that's a sober price for an end user to offer, but it's an interesting enough word - as we have seen by the variety of responses in this thread - that I wouldn't be surprised for you to get a substantially higher amount if the right end user swans by and their eyes bug out at the name.
Neat one. Hard call on the appraisal, but I like the name.
